-## Hello world
-
-![Alt text](https://travis-ci.org/machinezone/IXWebSocket.svg?branch=master)
-
-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.
-
-It is been used on big mobile video game titles sending and receiving tons of messages since 2017 (iOS and Android).
-
-Interested ? Go read the [docs](https://machinezone.github.io/IXWebSocket/) ! If things don't work as expected, please create an issue in github, or even better a pull request if you know how to fix your problem.
-
-IXWebSocket is actively being developed, check out the [changelog](CHANGELOG.md) 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).
-
-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.

+<h2 id="build">Build</h2>
+<h3 id="cmake">CMake</h3>
+<p>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.</p>
+<pre><code>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
+</code></pre>
+<p>Headers and a static library will be installed to the target dir.
+There is a unittest which can be executed by typing <code>make test</code>.</p>
+<p>Options for building:</p>
+<ul>
+<li><code>-DBUILD_SHARED_LIBS=ON</code> will build the unittest as a shared libary instead of a static library, which is the default</li>
+<li><code>-DUSE_ZLIB=1</code> will enable zlib support, required for http client + server + websocket per message deflate extension</li>
+<li><code>-DUSE_TLS=1</code> will enable TLS support</li>
+<li><code>-DUSE_OPEN_SSL=1</code> will use <a href="https://www.openssl.org/">openssl</a> for the TLS support (default on Linux and Windows). When using a custom version of openssl (say a prebuilt version, odd runtime problems can happens, as in #319, and special cmake trickery will be required (see this <a href="https://github.com/machinezone/IXWebSocket/issues/175#issuecomment-620231032">comment</a>)</li>
+<li><code>-DUSE_MBED_TLS=1</code> will use <a href="https://tls.mbed.org/">mbedlts</a> for the TLS support</li>
+<li><code>-DUSE_WS=1</code> will build the ws interactive command line tool</li>
+<li><code>-DUSE_TEST=1</code> will build the unittest</li>
+</ul>
+<p>If you are on Windows, look at the <a href="https://github.com/machinezone/IXWebSocket/blob/master/appveyor.yml">appveyor</a> file (not maintained much though) or rather the <a href="https://github.com/machinezone/IXWebSocket/blob/master/.github/workflows/unittest_windows.yml">github actions</a> which have instructions for building dependencies.</p>
+<p>It is also possible to externally include the project, so that everything is fetched over the wire when you build like so:</p>
+<pre><code>    ExternalProject_Add(
+        IXWebSocket
+        GIT_REPOSITORY https://github.com/machinezone/IXWebSocket.git
+        ...
+    )
+</code></pre>
+<h3 id="vcpkg">vcpkg</h3>
+<p>It is possible to get IXWebSocket through Microsoft <a href="https://github.com/microsoft/vcpkg">vcpkg</a>.</p>
+<pre><code>vcpkg install ixwebsocket
+</code></pre>
+<p>To use the installed package within a cmake project, use the following:</p>
+<pre><code class="language-cmake"> set(CMAKE_TOOLCHAIN_FILE &quot;$ENV{VCPKG_ROOT}/scripts/buildsystems/vcpkg.cmake&quot; CACHE STRING &quot;&quot;) # this is super important in order for cmake to include the vcpkg search/lib paths!
+
+ # find library and its headers
+ find_path(IXWEBSOCKET_INCLUDE_DIR ixwebsocket/IXWebSocket.h)
+ find_library(IXWEBSOCKET_LIBRARY ixwebsocket)
+ # include headers
+ include_directories(${IXWEBSOCKET_INCLUDE_DIR})
+ # ...
+ target_link_libraries(${PROJECT_NAME} ... ${IXWEBSOCKET_LIBRARY}) # Cmake will automatically fail the generation if the lib was not found, i.e is set to NOTFOUND
+
+</code></pre>
+<h3 id="conan">Conan</h3>
+<p><a href="https://bintray.com/conan/conan-center/ixwebsocket%3A_/_latestVersion"> <img alt="Download" src="https://api.bintray.com/packages/conan/conan-center/ixwebsocket%3A_/images/download.svg" /> </a></p>

+<p>Note that the version listed here might not be the latest one. See Bintray or the recipe itself for the latest version. If you're migrating from the previous, custom Bintray remote, note that the package reference <em>has</em> to be lower-case.</p>
+<h3 id="docker">Docker</h3>
+<p>There is a Dockerfile for running the unittest on Linux, and to run the <code>ws</code> tool. It is also available on the docker registry.</p>
+<pre><code>docker run docker.pkg.github.com/machinezone/ixwebsocket/ws:latest --help
+</code></pre>
+<p>To use docker-compose you must make a docker container first.</p>

+<h2 id="implementation-details">Implementation details</h2>
+<h3 id="per-message-deflate-compression">Per Message Deflate compression.</h3>
+<p>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.</p>
+<h3 id="tlsssl">TLS/SSL</h3>
+<p>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 and mbedTLS can be used on Android, Linux and Windows.</p>
+<p>If you are using OpenSSL, try to be on a version higher than 1.1.x as there there are thread safety problems with 1.0.x.</p>
+<h3 id="polling-and-background-thread-work">Polling and background thread work</h3>
+<p>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 <a href="http://man7.org/linux/man-pages/man2/select.2.html">system</a> 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 <a href="https://linux.die.net/man/2/select_tut">select law</a>. 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 <a href="https://stackoverflow.com/questions/1981372/are-parallel-calls-to-send-recv-on-the-same-socket-valid">possible</a> since system socket implementations allow concurrent read/writes.</p>
+<h3 id="automatic-reconnection">Automatic reconnection</h3>
+<p>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.</p>
+<h3 id="large-messages">Large messages</h3>
+<p>Large frames are broken up into smaller chunks or messages to avoid filling up the os tcp buffers, which is permitted thanks to WebSocket <a href="https://tools.ietf.org/html/rfc6455#section-5.4">fragmentation</a>. Messages up to 1G were sent and received succesfully.</p>
+<h3 id="testing">Testing</h3>
+<p>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.</p>
+<p>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.</p>
+<p>The regression test is running after each commit on github actions for multiple configurations.</p>
+<h2 id="limitations">Limitations</h2>
+<ul>
+<li>On some configuration (mostly 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. With mbedtls the message will contain <code>error in handshake : X509 - Certificate verification failed, e.g. CRL, CA or signature check failed</code>.</li>
+<li>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 <code>recv</code> and <code>send</code> error codes. <a href="https://stackoverflow.com/questions/14782143/linux-socket-how-to-detect-disconnected-network-in-a-client-program">Here</a> 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.</li>
+<li>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.</li>
+</ul>
+<h2 id="c-code-organization">C++ code organization</h2>
+<p>Here is a simplistic diagram which explains how the code is structured in term of class/modules.</p>

+|                       | Start the receiving Background thread. Auto reconnection. Simple websocket Ping.
+|  IXWebSocket          | Interface used by C++ test clients. No IX dependencies.
+|                       |
+-----------------------+
+|                       |
+|  IXWebSocketServer    | Run a server and give each connections its own WebSocket object.
+|                       | Each connection is handled in a new OS thread.
+|                       |
+-----------------------+ --- Private
+|                       |
+|  IXWebSocketTransport | Low level websocket code, framing, managing raw socket. Adapted from easywsclient.
+|                       |
+-----------------------+
+|                       |
+|  IXWebSocketHandshake | Establish the connection between client and server.
+|                       |
+-----------------------+
+|                       |
+|  IXWebSocket          | ws://  Unencrypted Socket handler
+|  IXWebSocketAppleSSL  | wss:// TLS encrypted Socket AppleSSL handler. Used on iOS and macOS
+|  IXWebSocketOpenSSL   | wss:// TLS encrypted Socket OpenSSL handler.  Used on Android and Linux
+|                       |                                               Can be used on macOS too.
+-----------------------+
+|                       |
+|  IXSocketConnect      | Connect to the remote host (client).
+|                       |
+-----------------------+
+|                       |
+|  IXDNSLookup          | Does DNS resolution asynchronously so that it can be interrupted.

-
-## [5.1.0] - 2019-08-31
-
- ws autobahn / Add code to test websocket client compliance with the autobahn test-suite
- add utf-8 validation code, not hooked up properly yet
- Ping received with a payload too large (> 125 bytes) trigger a connection closure
- cobra / add tracking about published messages
- cobra / publish returns a message id, that can be used when
- cobra / new message type in the message received handler when publish/ok is received (can be used to implement an ack system).
-
-## [5.0.9] - 2019-08-30
-
- User-Agent header is set when not specified.
- New option to cap the max wait between reconnection attempts. Still default to 10s. (setMaxWaitBetweenReconnectionRetries).
-
-```
-ws connect --max_wait 5000 ws://example.com # will only wait 5 seconds max between reconnection attempts
-```
-
-## [5.0.7] - 2019-08-23
- WebSocket: add new option to pass in extra HTTP headers when connecting.
- `ws connect` add new option (-H, works like [curl](https://stackoverflow.com/questions/356705/how-to-send-a-header-using-a-http-request-through-a-curl-call)) to pass in extra HTTP headers when connecting
-
-If you run against `ws echo_server` you will see the headers being received printed in the terminal.
-```
-ws connect -H "foo: bar" -H "baz: buz" ws://127.0.0.1:8008
-```
-
- CobraConnection: sets a unique id field for all messages sent to [cobra](https://github.com/machinezone/cobra).
- CobraConnection: sets a counter as a field for each event published.
-
-## [5.0.6] - 2019-08-22
- Windows: silly compile error (poll should be in the global namespace)
-
-## [5.0.5] - 2019-08-22
- Windows: use select instead of WSAPoll, through a poll wrapper
-
-## [5.0.4] - 2019-08-20
- Windows build fixes (there was a problem with the use of ::poll that has a different name on Windows (WSAPoll))
-
-## [5.0.3] - 2019-08-14
- CobraMetricThreadedPublisher _enable flag is an atomic, and CobraMetricsPublisher is enabled by default
-
-## [5.0.2] - 2019-08-01
- ws cobra_subscribe has a new -q (quiet) option
- ws cobra_subscribe knows to and display msg stats (count and # of messages received per second)
- ws cobra_subscribe, cobra_to_statsd and cobra_to_sentry commands have a new option, --filter to restrict the events they want to receive
-
-## [5.0.1] - 2019-07-25
- ws connect command has a new option to send in binary mode (still default to text)
- ws connect command has readline history thanks to libnoise-cpp. Now ws connect one can use using arrows to lookup previous sent messages and edit them
-
-## [5.0.0] - 2019-06-23
-### Changed
- New HTTP server / still very early. ws gained a new command, httpd can run a simple webserver serving local files.
- IXDNSLookup. Uses weak pointer + smart_ptr + shared_from_this instead of static sets + mutex to handle object going away before dns lookup has resolved
- cobra_to_sentry / backtraces are reversed and line number is not extracted correctly
- mbedtls and zlib are searched with find_package, and we use the vendored version if nothing is found
- travis CI uses g++ on Linux
-
-## [4.0.0] - 2019-06-09
-### Changed
- WebSocket::send() sends message in TEXT mode by default
- WebSocketMessage sets a new binary field, which tells whether the received incoming message is binary or text
- WebSocket::send takes a third arg, binary which default to true (can be text too)
- WebSocket callback only take one object, a const ix::WebSocketMessagePtr& msg
- Add explicit WebSocket::sendBinary method
- New headers + WebSocketMessage class to hold message data, still not used across the board
- Add test/compatibility folder with small servers and clients written in different languages and different libraries to test compatibility.
- ws echo_server has a -g option to print a greeting message on connect
- IXSocketMbedTLS: better error handling in close and connect
-
-## [3.1.2] - 2019-06-06
-### Added
- ws connect has a -x option to disable per message deflate
- Add WebSocket::disablePerMessageDeflate() option.
-
-## [3.0.0] - 2019-06-xx

-## 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.

-## 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 platoform, with different sanitizers such as thread sanitizer to catch data races or the undefined behavior sanitizer.
-
-The regression test is running after each commit on travis.
-
-## Limitations
-
-* On Windows TLS is not setup yet to validate certificates.
-* 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
-
-## Example code
-
-```
-# 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.

-# 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.
-
-```
-#include <ixwebsocket/IXNetSystem.h>
-
-int main()
-{
-    ix::initNetSystem();
-
-    ...
-
-    ix::uninitNetSystem();
-    return 0;
-}
-```
-
-## WebSocket client API
-
-```
-#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`.
-
-```
-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.
-
-```
-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.
-
-```
-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([](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.
-
-```
-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);
-```
-
-### Supply extra HTTP headers.
-
-You can set extra HTTP headers to be sent during the WebSocket handshake.
-
-```
-WebSocketHttpHeaders headers;
-headers["foo"] = "bar";
-webSocket.setExtraHeaders(headers);
-```
-
-### 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.
-
-```
-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.
-
-```
-webSocket.setMaxWaitBetweenReconnectionRetries(5 * 1000); // 5000ms = 5s
-uint32_t m = webSocket.getMaxWaitBetweenReconnectionRetries();
-```

+<p>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.</p>
+<p>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. Note that the MinGW compiler is not supported at this point. Two important design goals are simplicity and correctness.</p>
+<p>A bad security bug affecting users compiling with SSL enabled and OpenSSL as the backend was just fixed in newly released version 11.0.0. Please upgrade ! (more details in the <a href="PR">https://github.com/machinezone/IXWebSocket/pull/250</a>.</p>

+<p>Interested? Go read the <a href="https://machinezone.github.io/IXWebSocket/">docs</a>! 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.</p>
+<p>IXWebSocket is actively being developed, check out the <a href="https://machinezone.github.io/IXWebSocket/CHANGELOG/">changelog</a> 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 <a href="https://github.com/machinezone/cobra">cobra</a>.</p>
+<p>IXWebSocket client code is autobahn compliant beginning with the 6.0.0 version. See the current <a href="https://bsergean.github.io/autobahn/reports/clients/index.html">test results</a>. Some tests are still failing in the server code.</p>
+<p>Starting with the 11.0.8 release, IXWebSocket should be fully C++11 compatible.</p>

+<p><a href="https://github.com/bsergean/uvweb">uvweb</a> is a library written by the IXWebSocket author which is built on top of <a href="https://github.com/skypjack/uvw">uvw</a>, which is a C++ wrapper for <a href="https://libuv.org/">libuv</a>. It has more dependencies and does not support SSL at this point, but it can be used to open multiple connections within a single OS thread thanks to libuv.</p>
