 ## Hello world
 
-![Build status](https://github.com/machinezone/IXWebSocket/workflows/unittest/badge.svg)
-
 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). It was tested on macOS, iOS, Linux, Android, Windows and FreeBSD. Two important design goals are simplicity and correctness.
+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.

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.

 ## 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.

 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.

+## 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.

+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...

-### 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

+## TLS support and configuration
+
+To leverage TLS features, the library must be compiled with the option `USE_TLS=1`.
+
+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.
+
+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", // as a file, or in memory buffer in PEM format
+    .tls = true // required in server mode
+});
+```
+
+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.
+ - If the value contain the special value `-----BEGIN CERTIFICATE-----`, the value will be read from memory, and not from a file. This is convenient on platforms like Android where reading / writing to the file system can be challenging without proper permissions, or without knowing the location of a temp directory.
+
+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

 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.
+
+```json
+{
+        "remote_urls": {
+                "echo.jeanserge.com": "ws://localhost:8008",
+                "bavarde.jeanserge.com": "ws://localhost:5678"
+        }
+}
+```
+The --config_path option is required to instruct ws proxy_server to read that file.
