WebSocket Echo Server and Client

This example shows how to set and get custom HTTP headers for using during the initial WebSocket opening handshake.

Running

Run the server by doing

python server.py debug

Run the client by doing

python client.py ws://127.0.0.1:9000 debug

The client will send a custom HTTP header MyCustomClientHeader during the initial WebSocket opening handshake:

    User-Agent: AutobahnPython/0.6.0
    Host: 127.0.0.1:9000
    Upgrade: WebSocket
    Connection: Upgrade
    Pragma: no-cache
    Cache-Control: no-cache
    MyCustomClientHeader: Bazbar
    Sec-WebSocket-Key: tI9KmKOGOAGTxgWfVn13zg==
    Sec-WebSocket-Version: 13

The server will respond with custom HTTP headers

    HTTP/1.1 101 Switching Protocols
    Server: AutobahnPython/0.6.0
    Upgrade: WebSocket
    Connection: Upgrade
    MyCustomServerHeader: Foobar
    MyCustomDynamicServerHeader1: Hello
    MyCustomDynamicServerHeader2: Bazbar
    Sec-WebSocket-Accept: pQklbTbzxoUDuSDHpiYJThfd4vo=

where MyCustomServerHeader is a custom header sent to any connecting client (defined on the WebSocketServerFactory) and MyCustomDynamicServerHeader1 and MyCustomDynamicServerHeader2 are custom headers which values can be specific to the connecting client (and set within onConnect).
