-IXWebSocket is a C++ library for WebSocket client and server development. It has minimal dependencies (no boost), is very simple to use and support everything you'll likely need for websocket dev (SSL, deflate compression, compiles on most platforms, etc...). HTTP client and server code is also available, but it hasn't received as much testing.
+## Introduction
 
-It is been used on big mobile video game titles sending and receiving tons of messages since 2017 (iOS and Android). It was tested on macOS, iOS, Linux, Android, Windows and FreeBSD. Two important design goals are simplicity and correctness.
+[*WebSocket*](https://en.wikipedia.org/wiki/WebSocket) is a computer communications protocol, providing full-duplex and bi-directionnal communication channels over a single TCP connection. *IXWebSocket* is a C++ library for client and server Websocket communication, and for client HTTP communication. The code is derived from [easywsclient](https://github.com/dhbaird/easywsclient) and from the [Satori C SDK](https://github.com/satori-com/satori-rtm-sdk-c). It has been tested on the following platforms.
 
-```cpp
-// Required on Windows
-ix::initNetSystem();
+* macOS
+* iOS
+* Linux
+* Android
+* Windows (no TLS)
 
-// Our websocket object
+## Examples
+
+The [*ws*](https://github.com/machinezone/IXWebSocket/tree/master/ws) folder countains many interactive programs for chat, [file transfers](https://github.com/machinezone/IXWebSocket/blob/master/ws/ws_send.cpp), [curl like](https://github.com/machinezone/IXWebSocket/blob/master/ws/ws_http_client.cpp) http clients, demonstrating client and server usage.
+
+Here is what the client API looks like.
+
+```
 ix::WebSocket webSocket;
 
 std::string url("ws://localhost:8080/");
 webSocket.setUrl(url);
 
-// Setup a callback to be fired (in a background thread, watch out for race conditions !)
-// when a message or an event (open, close, error) is received
-webSocket.setOnMessageCallback([](const ix::WebSocketMessagePtr& msg)
+// Optional heart beat, sent every 45 seconds when there is not any traffic
+// to make sure that load balancers do not kill an idle connection.
+webSocket.setHeartBeatPeriod(45);
+
+// Setup a callback to be fired when a message or an event (open, close, error) is received
+webSocket.setOnMessageCallback(
+    [](ix::WebSocketMessageType messageType,
+       const std::string& str,
+       size_t wireSize,
+       const ix::WebSocketErrorInfo& error,
+       const ix::WebSocketOpenInfo& openInfo,
+       const ix::WebSocketCloseInfo& closeInfo)
     {
-        if (msg->type == ix::WebSocketMessageType::Message)
+        if (messageType == ix::WebSocketMessageType::Message)
         {
-            std::cout << msg->str << std::endl;
+            std::cout << str << std::endl;
         }
-    }
-);
+});
 
 // Now that our callback is setup, we can start our background thread and receive messages
 webSocket.start();
 
-// Send a message to the server (default to TEXT mode)
+// Send a message to the server (default to BINARY mode)
 webSocket.send("hello world");
+
+// The message can be sent in TEXT mode
+webSocket.sendText("hello again");
+
+// ... finally ...
+
+// Stop the connection
+webSocket.stop()
 ```
 
-Interested? Go read the [docs](https://machinezone.github.io/IXWebSocket/)! If things don't work as expected, please create an issue on GitHub, or even better a pull request if you know how to fix your problem.
+Here is what the server API looks like. Note that server support is very recent and subject to changes.
 
-IXWebSocket is actively being developed, check out the [changelog](https://machinezone.github.io/IXWebSocket/CHANGELOG/) to know what's cooking. If you are looking for a real time messaging service (the chat-like 'server' your websocket code will talk to) with many features such as history, backed by Redis, look at [cobra](https://github.com/machinezone/cobra).
+```
+// Run a server on localhost at a given port.
+// Bound host name, max connections and listen backlog can also be passed in as parameters.
+ix::WebSocketServer server(port);
 
-IXWebSocket client code is autobahn compliant beginning with the 6.0.0 version. See the current [test results](https://bsergean.github.io/IXWebSocket/autobahn/index.html). Some tests are still failing in the server code.

+auto uploadSize = std::get<5>(out);
+auto downloadSize = std::get<6>(out);
+```
+
+## Build
+
+CMakefiles for the library and the examples are available. This library has few dependencies, so it is possible to just add the source files into your project. Otherwise the usual way will suffice.
+
+```
+mkdir build # make a build dir so that you can build out of tree.
+cd build
+cmake ..
+make -j
+make install # will install to /usr/local on Unix, on macOS it is a good idea to sudo chown -R `whoami`:staff /usr/local
+```
+
+Headers and a static library will be installed to the target dir.
+
+A [conan](https://conan.io/) file is available at [conan-IXWebSocket](https://github.com/Zinnion/conan-IXWebSocket).
+
+There is a unittest which can be executed by typing `make test`.
+
+There is a Dockerfile for running some code on Linux. To use docker-compose you must make a docker container first.
+
+```
+$ make docker
+...
+$ docker compose up &
+...
+$ docker exec -it ixwebsocket_ws_1 bash
+app@ca2340eb9106:~$ ws --help
+ws is a websocket tool
+...
+```
+
+Finally you can build and install the `ws command line tool` with Homebrew. The homebrew version might be slightly out of date.
+
+```
+brew tap bsergean/IXWebSocket
+brew install IXWebSocket
+```
+
+## Implementation details
+
+### Per Message Deflate compression.
+
+The per message deflate compression option is supported. It can lead to very nice bandbwith savings (20x !) if your messages are similar, which is often the case for example for chat applications. All features of the spec should be supported.
+
+### TLS/SSL
+
+Connections can be optionally secured and encrypted with TLS/SSL when using a wss:// endpoint, or using normal un-encrypted socket with ws:// endpoints. AppleSSL is used on iOS and macOS, and OpenSSL is used on Android and Linux.
+
+### Polling and background thread work
+
+No manual polling to fetch data is required. Data is sent and received instantly by using a background thread for receiving data and the select [system](http://man7.org/linux/man-pages/man2/select.2.html) call to be notified by the OS of incoming data. No timeout is used for select so that the background thread is only woken up when data is available, to optimize battery life. This is also the recommended way of using select according to the select tutorial, section [select law](https://linux.die.net/man/2/select_tut). Read and Writes to the socket are non blocking. Data is sent right away and not enqueued by writing directly to the socket, which is [possible](https://stackoverflow.com/questions/1981372/are-parallel-calls-to-send-recv-on-the-same-socket-valid) since system socket implementations allow concurrent read/writes. However concurrent writes need to be protected with mutex.
+
+### Automatic reconnection
+
+If the remote end (server) breaks the connection, the code will try to perpetually reconnect, by using an exponential backoff strategy, capped at one retry every 10 seconds.
+
+### Large messages
+
+Large frames are broken up into smaller chunks or messages to avoid filling up the os tcp buffers, which is permitted thanks to WebSocket [fragmentation](https://tools.ietf.org/html/rfc6455#section-5.4). Messages up to 1G were sent and received succesfully.
+
+## Limitations
+
+* No utf-8 validation is made when sending TEXT message with sendText()
+* Automatic reconnection works at the TCP socket level, and will detect remote end disconnects. However, if the device/computer network become unreachable (by turning off wifi), it is quite hard to reliably and timely detect it at the socket level using `recv` and `send` error codes. [Here](https://stackoverflow.com/questions/14782143/linux-socket-how-to-detect-disconnected-network-in-a-client-program) is a good discussion on the subject. This behavior is consistent with other runtimes such as node.js. One way to detect a disconnected device with low level C code is to do a name resolution with DNS but this can be expensive. Mobile devices have good and reliable API to do that.
+* The server code is using select to detect incoming data, and creates one OS thread per connection. This is not as scalable as strategies using epoll or kqueue.
+
+## C++ code organization
+
+Here is a simplistic diagram which explains how the code is structured in term of class/modules.
+
+```

+
+## API
+
+### Sending messages
+
+`websocket.send("foo")` will send a message.
+
+If the connection was closed and sending failed, the return value will be set to false.
+
+### ReadyState
+
+`getReadyState()` returns the state of the connection. There are 4 possible states.
+
+1. ReadyState::Connecting - The connection is not yet open.
+2. ReadyState::Open       - The connection is open and ready to communicate.
+3. ReadyState::Closing    - The connection is in the process of closing.
+4. ReadyState::Closed     - The connection is closed or could not be opened.
+
+### Open and Close notifications
+
+The onMessage event will be fired when the connection is opened or closed. This is similar to the [Javascript browser API](https://developer.mozilla.org/en-US/docs/Web/API/WebSocket), which has `open` and `close` events notification that can be registered with the browser `addEventListener`.
+
+```
+webSocket.setOnMessageCallback(
+    [](ix::WebSocketMessageType messageType,
+       const std::string& str,
+       size_t wireSize,
+       const ix::WebSocketErrorInfo& error,
+       const ix::WebSocketOpenInfo& openInfo,
+       const ix::WebSocketCloseInfo& closeInfo)
+    {
+        if (messageType == ix::WebSocketMessageType::Open)
+        {
+            std::cout << "send greetings" << std::endl;
+
+            // Headers can be inspected (pairs of string/string)
+            std::cout << "Handshake Headers:" << std::endl;
+            for (auto it : headers)
+            {
+                std::cout << it.first << ": " << it.second << std::endl;
+            }
+        }
+        else if (messageType == ix::WebSocketMessageType::Close)
+        {
+            std::cout << "disconnected" << std::endl;
+
+            // The server can send an explicit code and reason for closing.
+            // This data can be accessed through the closeInfo object.
+            std::cout << closeInfo.code << std::endl;
+            std::cout << closeInfo.reason << std::endl;
+        }
+    }
+);
+```
+
+### Error notification
+
+A message will be fired when there is an error with the connection. The message type will be `ix::WebSocketMessageType::Error`. Multiple fields will be available on the event to describe the error.
+
+```
+webSocket.setOnMessageCallback(
+    [](ix::WebSocketMessageType messageType,
+       const std::string& str,
+       size_t wireSize,
+       const ix::WebSocketErrorInfo& error,
+       const ix::WebSocketOpenInfo& openInfo,
+       const ix::WebSocketCloseInfo& closeInfo)
+    {
+        if (messageType == ix::WebSocketMessageType::Error)
+        {
+            std::stringstream ss;
+            ss << "Error: "         << error.reason      << std::endl;
+            ss << "#retries: "      << event.retries     << std::endl;
+            ss << "Wait time(ms): " << event.wait_time   << std::endl;
+            ss << "HTTP Status: "   << event.http_status << std::endl;
+            std::cout << ss.str() << std::endl;
+        }
+    }
+);
+```
+
+### start, stop
+
+1. `websocket.start()` connect to the remote server and starts the message receiving background thread.
+2. `websocket.stop()` disconnect from the remote server and closes the background thread.
+
+### Configuring the remote url
+
+The url can be set and queried after a websocket object has been created. You will have to call `stop` and `start` if you want to disconnect and connect to that new url.
+
+```
+std::string url("wss://example.com");
+websocket.configure(url);
+```
+
+### Ping/Pong support
+
+Ping/pong messages are used to implement keep-alive. 2 message types exists to identify ping and pong messages. Note that when a ping message is received, a pong is instantly send back as requested by the WebSocket spec.
+
+```
+webSocket.setOnMessageCallback(
+    [](ix::WebSocketMessageType messageType,
+       const std::string& str,
+       size_t wireSize,
+       const ix::WebSocketErrorInfo& error,
+       const ix::WebSocketOpenInfo& openInfo,
+       const ix::WebSocketCloseInfo& closeInfo)
+    {
+        if (messageType == ix::WebSocketMessageType::Ping ||
+            messageType == ix::WebSocketMessageType::Pong)
+        {
+            std::cout << "pong data: " << str << std::endl;
+        }
+    }
+);
+```
+
+A ping message can be sent to the server, with an optional data string.
+
+```
+websocket.ping("ping data, optional (empty string is ok): limited to 125 bytes long");
+```
+
+### Heartbeat.
+
+You can configure an optional heart beat / keep-alive, sent every 45 seconds
+when there is no any traffic to make sure that load balancers do not kill an
+idle connection.
+
+```
+webSocket.setHeartBeatPeriod(45);
+```

-## Build
-
-### CMake
-
-CMakefiles for the library and the examples are available. This library has few dependencies, so it is possible to just add the source files into your project. Otherwise the usual way will suffice.
-
-```
-mkdir build # make a build dir so that you can build out of tree.
-cd build
-cmake -DUSE_TLS=1 ..
-make -j
-make install # will install to /usr/local on Unix, on macOS it is a good idea to sudo chown -R `whoami`:staff /usr/local
-```
-
-Headers and a static library will be installed to the target dir.
-There is a unittest which can be executed by typing `make test`.
-
-Options for building:
-
-* `-DUSE_TLS=1` will enable TLS support
-* `-DUSE_MBED_TLS=1` will use [mbedlts](https://tls.mbed.org/) for the TLS support (default on Windows)
-* `-DUSE_WS=1` will build the ws interactive command line tool
-
-If you are on Windows, look at the [appveyor](https://github.com/machinezone/IXWebSocket/blob/master/appveyor.yml) file that has instructions for building dependencies.
-
-### vcpkg
-
-It is possible to get IXWebSocket through Microsoft [vcpkg](https://github.com/microsoft/vcpkg).
-
-```
-vcpkg install ixwebsocket
-```
-
-### Conan
-
-Support for building with conan was contributed by Olivia Zoe (thanks!). The package name to reference is `IXWebSocket/5.0.0@LunarWatcher/stable`, and a list of the uploaded versions is available on [Bintray](https://bintray.com/oliviazoe0/conan-packages/IXWebSocket%3ALunarWatcher). The package is in the process to be published to the official conan package repo, but in the meantime, it can be accessed by adding a new remote
-
-```
-conan remote add remote_name_here https://api.bintray.com/conan/oliviazoe0/conan-packages
-```
-
-### Docker
-
-There is a Dockerfile for running the unittest on Linux, and to run the `ws` tool. It is also available on the docker registry.
-
-```
-docker run bsergean/ws
-```
-
-To use docker-compose you must make a docker container first.
-
-```
-$ make docker
-...
-$ docker compose up &
-...
-$ docker exec -it ixwebsocket_ws_1 bash
-app@ca2340eb9106:~$ ws --help
-ws is a websocket tool

-## General
-
-[cobra](https://github.com/machinezone/cobra) is a real time messaging server. The `ws` utility can run a cobra server (named snake), and has client to publish and subscribe to a cobra server.
-
-Bring up 3 terminals and run a server, a publisher and a subscriber in each one. As you publish data you should see it being received by the subscriber. You can run `redis-cli MONITOR` too to see how redis is being used.
-
-### Server
-
-You will need to have a redis server running locally. To run the server:
-
-```bash
-$ cd <ixwebsocket-top-level-folder>/ixsnake/ixsnake
-$ ws snake

-## Implementation details
-
-### Per Message Deflate compression.
-
-The per message deflate compression option is supported. It can lead to very nice bandbwith savings (20x !) if your messages are similar, which is often the case for example for chat applications. All features of the spec should be supported.
-
-### TLS/SSL
-
-Connections can be optionally secured and encrypted with TLS/SSL when using a wss:// endpoint, or using normal un-encrypted socket with ws:// endpoints. AppleSSL is used on iOS and macOS, OpenSSL is used on Android and Linux, mbedTLS is used on Windows.
-
-### Polling and background thread work
-
-No manual polling to fetch data is required. Data is sent and received instantly by using a background thread for receiving data and the select [system](http://man7.org/linux/man-pages/man2/select.2.html) call to be notified by the OS of incoming data. No timeout is used for select so that the background thread is only woken up when data is available, to optimize battery life. This is also the recommended way of using select according to the select tutorial, section [select law](https://linux.die.net/man/2/select_tut). Read and Writes to the socket are non blocking. Data is sent right away and not enqueued by writing directly to the socket, which is [possible](https://stackoverflow.com/questions/1981372/are-parallel-calls-to-send-recv-on-the-same-socket-valid) since system socket implementations allow concurrent read/writes. However concurrent writes need to be protected with mutex.
-
-### Automatic reconnection
-
-If the remote end (server) breaks the connection, the code will try to perpetually reconnect, by using an exponential backoff strategy, capped at one retry every 10 seconds. This behavior can be disabled.
-
-### Large messages
-
-Large frames are broken up into smaller chunks or messages to avoid filling up the os tcp buffers, which is permitted thanks to WebSocket [fragmentation](https://tools.ietf.org/html/rfc6455#section-5.4). Messages up to 1G were sent and received succesfully.
-
-### Testing
-
-The library has an interactive tool which is handy for testing compatibility ith other libraries. We have tested our client against Python, Erlang, Node.js, and C++ websocket server libraries.
-
-The unittest tries to be comprehensive, and has been running on multiple platforms, with different sanitizers such as a thread sanitizer to catch data races or the undefined behavior sanitizer.
-
-The regression test is running after each commit on travis.
-
-## Limitations
-
-* On Windows and Android certificate validation needs to be setup so that SocketTLSOptions.caFile point to a pem file, such as the one distributed by Firefox. Unless that setup is done connecting to a wss endpoint will display an error. On Windows with mbedtls the message will contain `error in handshake : X509 - Certificate verification failed, e.g. CRL, CA or signature check failed`.
-* There is no convenient way to embed a ca cert.
-* Automatic reconnection works at the TCP socket level, and will detect remote end disconnects. However, if the device/computer network become unreachable (by turning off wifi), it is quite hard to reliably and timely detect it at the socket level using `recv` and `send` error codes. [Here](https://stackoverflow.com/questions/14782143/linux-socket-how-to-detect-disconnected-network-in-a-client-program) is a good discussion on the subject. This behavior is consistent with other runtimes such as node.js. One way to detect a disconnected device with low level C code is to do a name resolution with DNS but this can be expensive. Mobile devices have good and reliable API to do that.
-* The server code is using select to detect incoming data, and creates one OS thread per connection. This is not as scalable as strategies using epoll or kqueue.

-## Introduction
-
-[*WebSocket*](https://en.wikipedia.org/wiki/WebSocket) is a computer communications protocol, providing full-duplex and bi-directionnal communication channels over a single TCP connection. *IXWebSocket* is a C++ library for client and server Websocket communication, and for client and server HTTP communication. *TLS* aka *SSL* is supported. The code is derived from [easywsclient](https://github.com/dhbaird/easywsclient) and from the [Satori C SDK](https://github.com/satori-com/satori-rtm-sdk-c). It has been tested on the following platforms.
-
-* macOS
-* iOS
-* Linux
-* Android
-* Windows
-* FreeBSD
-
-## Example code
-
-```cpp
-// Required on Windows
-ix::initNetSystem();
-
-// Our websocket object
-ix::WebSocket webSocket;
-
-std::string url("ws://localhost:8080/");
-webSocket.setUrl(url);
-
-// Setup a callback to be fired when a message or an event (open, close, error) is received
-webSocket.setOnMessageCallback([](const ix::WebSocketMessagePtr& msg)
-    {
-        if (msg->type == ix::WebSocketMessageType::Message)
-        {
-            std::cout << msg->str << std::endl;
-        }
-    }
-);
-
-// Now that our callback is setup, we can start our background thread and receive messages
-webSocket.start();
-
-// Send a message to the server (default to TEXT mode)
-webSocket.send("hello world");
-```
-
-## Why another library?
-
-There are 2 main reasons that explain why IXWebSocket got written. First, we needed a C++ cross-platform client library, which should have few dependencies. What looked like the most solid one, [websocketpp](https://github.com/zaphoyd/websocketpp) did depend on boost and this was not an option for us. Secondly, there were other available libraries with fewer dependencies (C ones), but they required calling an explicit poll routine periodically to know if a client had received data from a server, which was not elegant.
-
-We started by solving those 2 problems, then we added server websocket code, then an HTTP client, and finally a very simple HTTP server.
-
-## Contributing
-
-IXWebSocket is developed on [GitHub](https://github.com/machinezone/IXWebSocket). We'd love to hear about how you use it; opening up an issue on GitHub is ok for that. If things don't work as expected, please create an issue on GitHub, or even better a pull request if you know how to fix your problem.

-# Examples
-
-The [*ws*](https://github.com/machinezone/IXWebSocket/tree/master/ws) folder countains many interactive programs for chat, [file transfers](https://github.com/machinezone/IXWebSocket/blob/master/ws/ws_send.cpp), [curl like](https://github.com/machinezone/IXWebSocket/blob/master/ws/ws_http_client.cpp) http clients, demonstrating client and server usage.
-
-## Windows note
-
-To use the network system on Windows, you need to initialize it once with *WSAStartup()* and clean it up with *WSACleanup()*. We have helpers for that which you can use, see below. This init would typically take place in your main function.
-
-```cpp
-#include <ixwebsocket/IXNetSystem.h>
-
-int main()
-{
-    ix::initNetSystem();
-
-    ...
-
-    ix::uninitNetSystem();
-    return 0;
-}
-```
-
-## WebSocket client API
-
-```cpp
-#include <ixwebsocket/IXWebSocket.h>
-
-...
-
-// Our websocket object
-ix::WebSocket webSocket;
-
-std::string url("ws://localhost:8080/");
-webSocket.setUrl(url);
-
-// Optional heart beat, sent every 45 seconds when there is not any traffic
-// to make sure that load balancers do not kill an idle connection.
-webSocket.setHeartBeatPeriod(45);
-
-// Per message deflate connection is enabled by default. You can tweak its parameters or disable it
-webSocket.disablePerMessageDeflate();
-
-// Setup a callback to be fired when a message or an event (open, close, error) is received
-webSocket.setOnMessageCallback([](const ix::WebSocketMessagePtr& msg)
-    {
-        if (msg->type == ix::WebSocketMessageType::Message)
-        {
-            std::cout << msg->str << std::endl;
-        }
-    }
-);
-
-// Now that our callback is setup, we can start our background thread and receive messages
-webSocket.start();
-
-// Send a message to the server (default to TEXT mode)
-webSocket.send("hello world");
-
-// The message can be sent in BINARY mode (useful if you send MsgPack data for example)
-webSocket.sendBinary("some serialized binary data");
-
-// ... finally ...
-
-// Stop the connection
-webSocket.stop()
-```
-
-### Sending messages
-
-`websocket.send("foo")` will send a message.
-
-If the connection was closed and sending failed, the return value will be set to false.
-
-### ReadyState
-
-`getReadyState()` returns the state of the connection. There are 4 possible states.
-
-1. ReadyState::Connecting - The connection is not yet open.
-2. ReadyState::Open       - The connection is open and ready to communicate.
-3. ReadyState::Closing    - The connection is in the process of closing.
-4. ReadyState::Closed     - The connection is closed or could not be opened.
-
-### Open and Close notifications
-
-The onMessage event will be fired when the connection is opened or closed. This is similar to the [JavaScript browser API](https://developer.mozilla.org/en-US/docs/Web/API/WebSocket), which has `open` and `close` events notification that can be registered with the browser `addEventListener`.
-
-```cpp
-webSocket.setOnMessageCallback([](const ix::WebSocketMessagePtr& msg)
-    {
-        if (msg->type == ix::WebSocketMessageType::Open)
-        {
-            std::cout << "send greetings" << std::endl;
-
-            // Headers can be inspected (pairs of string/string)
-            std::cout << "Handshake Headers:" << std::endl;
-            for (auto it : msg->headers)
-            {
-                std::cout << it.first << ": " << it.second << std::endl;
-            }
-        }
-        else if (msg->type == ix::WebSocketMessageType::Close)
-        {
-            std::cout << "disconnected" << std::endl;
-
-            // The server can send an explicit code and reason for closing.
-            // This data can be accessed through the closeInfo object.
-            std::cout << msg->closeInfo.code << std::endl;
-            std::cout << msg->closeInfo.reason << std::endl;
-        }
-    }
-);
-```
-
-### Error notification
-
-A message will be fired when there is an error with the connection. The message type will be `ix::WebSocketMessageType::Error`. Multiple fields will be available on the event to describe the error.
-
-```cpp
-webSocket.setOnMessageCallback([](const ix::WebSocketMessagePtr& msg)
-    {
-        if (msg->type == ix::WebSocketMessageType::Error)
-        {
-            std::stringstream ss;
-            ss << "Error: "         << msg->errorInfo.reason      << std::endl;
-            ss << "#retries: "      << msg->eventInfo.retries     << std::endl;
-            ss << "Wait time(ms): " << msg->eventInfo.wait_time   << std::endl;
-            ss << "HTTP Status: "   << msg->eventInfo.http_status << std::endl;
-            std::cout << ss.str() << std::endl;
-        }
-    }
-);
-```
-
-### start, stop
-
-1. `websocket.start()` connect to the remote server and starts the message receiving background thread.
-2. `websocket.stop()` disconnect from the remote server and closes the background thread.
-
-### Configuring the remote url
-
-The url can be set and queried after a websocket object has been created. You will have to call `stop` and `start` if you want to disconnect and connect to that new url.
-
-```cpp
-std::string url("wss://example.com");
-websocket.configure(url);
-```
-
-### Ping/Pong support
-
-Ping/pong messages are used to implement keep-alive. 2 message types exists to identify ping and pong messages. Note that when a ping message is received, a pong is instantly send back as requested by the WebSocket spec.
-
-```cpp
-webSocket.setOnMessageCallback([](const ix::WebSocketMessagePtr& msg)
-    {
-        if (msg->type == ix::WebSocketMessageType::Ping ||
-            msg->type == ix::WebSocketMessageType::Pong)
-        {
-            std::cout << "pong data: " << msg->str << std::endl;
-        }
-    }
-);
-```
-
-A ping message can be sent to the server, with an optional data string.
-
-```cpp
-websocket.ping("ping data, optional (empty string is ok): limited to 125 bytes long");
-```
-
-### Heartbeat.
-
-You can configure an optional heart beat / keep-alive, sent every 45 seconds
-when there is no any traffic to make sure that load balancers do not kill an
-idle connection.
-
-```cpp
-webSocket.setHeartBeatPeriod(45);
-```
-
-### Supply extra HTTP headers.
-
-You can set extra HTTP headers to be sent during the WebSocket handshake.
-
-```cpp
-WebSocketHttpHeaders headers;
-headers["foo"] = "bar";
-webSocket.setExtraHeaders(headers);
-```
-
-### Subprotocols
-
-You can specify subprotocols to be set during the WebSocket handshake. For more info you can refer to [this doc](https://hpbn.co/websocket/#subprotocol-negotiation).
-
-```cpp
-webSocket.addSubprotocol("appProtocol-v1");
-webSocket.addSubprotocol("appProtocol-v2");
-```
-
-The protocol that the server did accept is available in the open info `protocol` field.
-
-```cpp
-std::cout << "protocol: " << msg->openInfo.protocol << std::endl;
-```
-
-### Automatic reconnection
-
-Automatic reconnection kicks in when the connection is disconnected without the user consent. This feature is on by default and can be turned off.
-
-```cpp
-webSocket.enableAutomaticReconnection();  // turn on
-webSocket.disableAutomaticReconnection(); // turn off
-bool enabled = webSocket.isAutomaticReconnectionEnabled(); // query state
-```
-
-The technique to calculate wait time is called [exponential
-backoff](https://docs.aws.amazon.com/general/latest/gr/api-retries.html). Here
-are the default waiting times between attempts (from connecting with `ws connect ws://foo.com`)
-
-```
-> Connection error: Got bad status connecting to foo.com, status: 301, HTTP Status line: HTTP/1.1 301 Moved Permanently
-
-#retries: 1
-Wait time(ms): 100
-#retries: 2
-Wait time(ms): 200
-#retries: 3
-Wait time(ms): 400
-#retries: 4
-Wait time(ms): 800
-#retries: 5
-Wait time(ms): 1600
-#retries: 6
-Wait time(ms): 3200
-#retries: 7
-Wait time(ms): 6400
-#retries: 8
-Wait time(ms): 10000
-```
-
-The waiting time is capped by default at 10s between 2 attempts, but that value can be changed and queried.
-
-```cpp
-webSocket.setMaxWaitBetweenReconnectionRetries(5 * 1000); // 5000ms = 5s
-uint32_t m = webSocket.getMaxWaitBetweenReconnectionRetries();
-```
-
-### TLS support and configuration
-
-To leverage TLS features, the library must be compiled with the option `USE_TLS=1`.
-
-Then, secure sockets are automatically used when connecting to a `wss://*` url.
-
-Additional TLS options can be configured by passing a `ix::SocketTLSOptions` instance to the
-`setTLSOptions` on `ix::WebSocket` (or `ix::WebSocketServer` or `ix::HttpServer`)
-
-```cpp
-webSocket.setTLSOptions({
-    .certFile = "path/to/cert/file.pem",
-    .keyFile = "path/to/key/file.pem",
-    .caFile = "path/to/trust/bundle/file.pem"
-});
-```
-
-Specifying `certFile` and `keyFile` configures the certificate that will be used to communicate with TLS peers.
-
-On a client, this is only necessary for connecting to servers that require a client certificate.
-
-On a server, this is necessary for TLS support.
-
-Specifying `caFile` configures the trusted roots bundle file (in PEM format) that will be used to verify peer certificates.
- - The special value of `SYSTEM` (the default) indicates that the system-configured trust bundle should be used; this is generally what you want when connecting to any publicly exposed API/server.
- - The special value of `NONE` can be used to disable peer verification; this is only recommended to rule out certificate verification when testing connectivity.
-
-For a client, specifying `caFile` can be used if connecting to a server that uses a self-signed cert, or when using a custom CA in an internal environment.
-
-For a server, specifying `caFile` implies that:
-1. You require clients to present a certificate
-1. It must be signed by one of the trusted roots in the file
-

-## HTTP server API
-
-```cpp
-#include <ixwebsocket/IXHttpServer.h>
-
-ix::HttpServer server(port, hostname);
-
-auto res = server.listen();
-if (!res.first)
-{
-    std::cerr << res.second << std::endl;
-    return 1;
-}
-
-server.start();
-server.wait();
-```
-
-If you want to handle how requests are processed, implement the setOnConnectionCallback callback, which takes an HttpRequestPtr as input, and returns an HttpResponsePtr. You can look at HttpServer::setDefaultConnectionCallback for a slightly more advanced callback example.
-
-```cpp
-setOnConnectionCallback(
-    [this](HttpRequestPtr request,
-           std::shared_ptr<ConnectionState> /*connectionState*/) -> HttpResponsePtr
-    {
-        // Build a string for the response
-        std::stringstream ss;
-        ss << request->method
-           << " "
-           << request->uri;
-
-        std::string content = ss.str();
-
-        return std::make_shared<HttpResponse>(200, "OK",
-                                              HttpErrorCode::Ok,
-                                              WebSocketHttpHeaders(),
-                                              content);

-## Cobra client and server
-
-[cobra](https://github.com/machinezone/cobra) is a real time messenging server. ws has several sub-command to interact with cobra. There is also a minimal cobra compatible server named snake available.
-
-Below are examples on running a snake server and clients with TLS enabled (the server only works with the OpenSSL and the Mbed TLS backend for now).
-
-First, generate certificates.
-
-```
-$ cd /path/to/IXWebSocket
-$ cd ixsnake/ixsnake
-$ bash ../../ws/generate_certs.sh

-```
-
-Now run the snake server.
-
-```
-$ export certs=.certs

-    }
-  }
-}
-

-
-As a new connection comes in, such output should be printed

-To use OpenSSL on macOS, compile with `make ws_openssl`. First you will have to install OpenSSL libraries, which can be done with Homebrew. Use `make ws_mbedtls` accordingly to use MbedTLS.
