 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.

+
+## [10.2.3] - 2020-08-15

+
+## [10.2.2] - 2020-08-15
+
+(socket server) add a callback to the ConnectionState to be invoked when the connection is terminated. This will be used by the SocketServer in the future to know on time that the associated connection thread can be terminated.

+
+(socket server) do not create a select interrupt object everytime when polling for notifications while waiting for new connections, instead use a persistent one which is a member variable

+
+## [10.1.6] - 2020-08-06
+

+
+## [10.1.4] - 2020-08-02
+
+(ws) Add a new ws sub-command, echo_client. This command sends a message to an echo server, and send back to a server whatever message it does receive. When connecting to a local ws echo_server, on my MacBook Pro 2015 I can send/receive around 30,000 messages per second. (cf #235)
+
+## [10.1.3] - 2020-08-02

+(socket utility) move ix::getFreePort to ixwebsocket library
+
+## [10.0.0] - 2020-07-25
+
+(ixwebsocket server) change legacy api with 2 nested callbacks, so that the first api takes a weak_ptr<WebSocket> as its first argument
+
+## [9.10.7] - 2020-07-25
+
+(ixwebsocket) add WebSocketProxyServer, from ws. Still need to make the interface better.
+
+## [9.10.6] - 2020-07-24

+
+(websocket server) reset client websocket callback when the connection is closed
+
+## [9.10.0] - 2020-07-23
+
+(websocket server) add a new simpler API to handle client connections / that API does not trigger a memory leak while the previous one did
+
+## [9.9.3] - 2020-07-17
+
+(build) merge platform specific files which were used to have different implementations for setting a thread name into a single file, to make it easier to include every source files and build the ixwebsocket library (fix #226)
+
+## [9.9.2] - 2020-07-10
+
+(socket server) bump default max connection count from 32 to 128
+
+## [9.9.1] - 2020-07-10
+
+(snake) implement super simple stream sql expression support in snake server
+
 ## [9.9.0] - 2020-07-08

+## WebSocket Client performance
+
+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.
+
+### Receiving messages
+
+By using the push_server ws sub-command, the server will send the same message in a loop to any connected client.
+
+```
+ws push_server -q --send_msg 'yo'
+```
+
+By using the echo_client ws sub-command, with the -m (mute or no_send), we will display statistics on how many messages we can receive per second.
+
+```

 ### Sending messages

+`WebSocketSendInfo result = websocket.send("foo")` will send a message.
 
-If the connection was closed and sending failed, the return value will be set to false.
+If the connection was closed, sending will fail, and the success field of the result object  will be set to false. There could also be a compression error in which case the compressError field will be set to true. The payloadSize field and wireSize fields will tell you respectively how much bytes the message weight, and how many bytes were sent on the wire (potentially compressed + counting the message header (a few bytes).
+
+There is an optional progress callback that can be passed in as the second argument. If a message is large it will be fragmented into chunks which will be sent independantly. Everytime the we can write a fragment into the OS network cache, the callback will be invoked. If a user wants to cancel a slow send, false should be returned from within the callback.
+
+Here is an example code snippet copied from the ws send sub-command. Each fragment weights 32K, so the total integer is the wireSize divided by 32K. As an example if you are sending 32M of data, uncompressed, total will be 1000. current will be set to 0 for the first fragment, then 1, 2 etc...

 If you connect to ws://127.0.0.1:8008, the proxy will connect to ws://127.0.0.1:9000 and pass all traffic to this server.
 
+You can also use a more complex setup if you want to redirect to different websocket servers based on the hostname your client is trying to connect to. If you have multiple CNAME aliases that point to the same server.
+
+A JSON config file is used to express that mapping ; here connecting to echo.jeanserge.com will proxy the client to ws://localhost:8008 on the local machine (which actually runs ws echo_server), while connecting to bavarde.jeanserge.com will proxy the client to ws://localhost:5678 where a cobra python server is running. As a side note you will need a wildcard SSL certificate if you want to have SSL enabled on that machine.
