Re: Websocket Handshake failed

[Oliver Kroth <oliver.kroth@...>]

Hi,

You  have to create a coorect response key to signal the client that 
your server really does understand websockets.
Read the RFC for the details.

My Lua based web socket server's implementation is:

local key = cgi.header('sec-websocket-key')

key = require('sha1')( key .. '258EAFA5-E914-47DA-95CA-C5AB0DC85B11', 
false )
cgi.setheader( 'Sec-WebSocket-Accept', require('mime').b64( key ) )
