-## Introduction
-
-[*WebSocket*](https://en.wikipedia.org/wiki/WebSocket) is a computer communications protocol, providing full-duplex
-communication channels over a single TCP connection. *IXWebSocket* is a C++ library for client and server Websocket 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.
-
-* macOS
-* iOS
-* Linux
-* Android 
-* Windows (no TLS support yet)
-
-## Examples
-
-The ws folder countains many interactive programs for chat and file transfers 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);
-
-// Optional heart beat, sent every 45 seconds when there isn't 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::WebSocketCloseInfo& closeInfo,
-       const ix::WebSocketHttpHeaders& headers)
-    {
-        if (messageType == ix::WebSocket_MessageType_Message)
-        {
-            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
-webSocket.send("hello world");
-
-// ... finally ...
-
-// Stop the connection
-webSocket.stop()
-```
-
-Here is what the server API looks like. Note that server support is very recent and subject to changes.
-
-```
-// 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);
-
-server.setOnConnectionCallback(
-    [&server](std::shared_ptr<ix::WebSocket> webSocket)
-    {
-        webSocket->setOnMessageCallback(
-            [webSocket, &server](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::WebSocket_MessageType_Open)
-                {
-                    std::cerr << "New connection" << std::endl;
-                    std::cerr << "Uri: " << openInfo.uri << std::endl;
-                    std::cerr << "Headers:" << std::endl;
-                    for (auto it : openInfo.headers)
-                    {
-                        std::cerr << it.first << ": " << it.second << std::endl;
-                    }
-                }
-                else if (messageType == ix::WebSocket_MessageType_Message)
-                {
-                    // For an echo server, we just send back to the client whatever was received by the server
-                    // All connected clients are available in an std::set. See the broadcast cpp example.
-                    webSocket->send(str);
-                }
-            }
-        );
-    }
-);
-
-auto res = server.listen();
-if (!res.first)
-{
-    // Error handling
-    return 1;
-}
-
-// Run the server in the background. Server can be stoped by calling server.stop()
-server.start();
-
-// Block until server.stop() is called.
-server.wait();
-
-```
-
-## 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.
-
-There is a Dockerfile for running some code on Linux, and a unittest which can be executed by typing `make test`.
-
-## 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 500M were sent and received succesfully.
-
-## Limitations
-
-* There is no text support for sending data, only the binary protocol is supported. Sending json or text over the binary protocol works well.
-* 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 isn't as scalable as strategies using epoll or kqueue.

-## C++ code organization
-
-Here's 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. WebSocket_ReadyState_Connecting - The connection is not yet open.
-2. WebSocket_ReadyState_Open       - The connection is open and ready to communicate.
-3. WebSocket_ReadyState_Closing    - The connection is in the process of closing.
-4. WebSocket_MessageType_Close     - The connection is closed or couldn't 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::WebSocketCloseInfo& closeInfo,
-       const ix::WebSocketHttpHeaders& headers)
-    {
-        if (messageType == ix::WebSocket_MessageType_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::WebSocket_MessageType_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::WebSocket_MessageType_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::WebSocketCloseInfo& closeInfo,
-       const ix::WebSocketHttpHeaders& headers)
-    {
-        if (messageType == ix::WebSocket_MessageType_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::WebSocketCloseInfo& closeInfo,
-       const ix::WebSocketHttpHeaders& headers)
-    {
-        if (messageType == ix::WebSocket_MessageType_Ping ||
-            messageType == ix::WebSocket_MessageType_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 isn't any traffic to make sure that load balancers do not kill an
-idle connection.
-
-```
-webSocket.setHeartBeatPeriod(45);
-```

+<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

+<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_path(IXWEBSOCKET_INCLUDE_DIR ixwebsocket/IXWebSocket.h)
+ find_library(IXWEBSOCKET_LIBRARY ixwebsocket)
+ # include headers
+ include_directories(${IXWEBSOCKET_INCLUDE_DIR})
+ # ...

+<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>
+<pre><code>+-----------------------+ --- Public
+|                       | 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.
+|                       |

+<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>

+<p>We will run a client and a server on the same machine, connecting to localhost. This bench is run on a MacBook Pro from 2015. We can receive over 200,000 (small) messages per second, another way to put it is that it takes 5 micro-second to receive and process one message. This is an indication about the minimal latency to receive messages.</p>
+<h3 id="receiving-messages">Receiving messages</h3>
+<p>By using the push_server ws sub-command, the server will send the same message in a loop to any connected client.</p>
+<pre><code>ws push_server -q --send_msg 'yo'
