Anyone got and example of a cometd handshake over an http transport? I open a socket send my header and handshake request but always get an error saying no bayeux message found so I thinking the syntax of my handshake request is wrong so if anyone has a working example I'd appreciate some help.

    Well I found my mistakes this morning and the following client strings provide a successful response from the server: 
    cJSON_TestStr = [{"channel":"/meta/handshake","ext":{"mac":"00:04:20:23:a7:6d","rev":"7.7.1 r0","uuid":"null"},"supportedConnectionTypes":["long-polling","streaming"],"version":"1.0"}]

    Once the port is opened I send:
    SEND_STRING dvJSON,"'POST /cometd HTTP/1.1',STR_CRLF"; 
SEND_STRING dvJSON,"'Host: ',sJSON.sPlayer.cIP,':',itoa(sJSON.sPlayer.nPort),STR_CRLF";
SEND_STRING dvJSON,"'Referer: http://',sJSON.sPlayer.cIP,':',itoa(sJSON.sPlayer.nPort),'/',STR_CRLF";
SEND_STRING dvJSON,"'Cache-Control: no-cache',STR_CRLF";
SEND_STRING dvJSON,"'Pragma: no-cache',STR_CRLF";
SEND_STRING dvJSON,"'Content-Length: ',itoa(length_string(cJSON_TestStr)),STR_CRLF";
SEND_STRING dvJSON,"'Content-Type: application/json',STR_CRLF";
SEND_STRING dvJSON,"STR_CRLF";
SEND_STRING dvJSON,"cJSON_TestStr,STR_CRLF";
