> Asterisk websocket interface (res/res_http_websocket.c) works well for normal websockets (ws) but fails on secure - websockets (wss). The ast_websocket_read() function, first reads the header (14) bytes using first fread() call and then , for the remaining payload,  in a while loop, it first polls the raw-socket for the date before further reads. In the normal websocket, it is fine. But for the secure-websocket case, the underlying ssl_read() would have read the whole data, in the first fread() call (of course to decrypt ) and emptied the socket-fd. This would make the ast_websocket_read() to wait for data to appear on the socket.
> This patch enables the ast_websocket_read() function to read the whole available data at first and then wait for any fragmented packets. This makes the secure-websocket connection to work properly.
> This has been tested with  Chrome 31.0.1650.63.
