Help needed with uploading data to HTTP Server

Hi,

I need help with uploading(maybe posting is the proper word) data to my HTTP server.  I have read the document on uploading files but this is a simple data upload and the skeleton example isn't working me.  Can someone please tell me what I am doing wrong.

The HTTP Server doesn't have a webpage to accept FORM. It simple respond to upload data.  Example of the data in the body of the HTTP request i am require to upload is :
{
    "sensor 2": 1,
    "name": "contact sensor",
    "username": "sandy",
    "password": "access",
    "msg": [{"update"}]
} 
--------------------skeleton example in the document-------------
int my_CGI(HttpState * s)
{
  switch(http_getAction(s)) {
    case CGI_START:
    break;
    case CGI_DATA:
    break;
    case CGI_END:
    break;
    case CGI_EOF:
    break;
    case CGI_ABORT:
    break;
  }
  return 0;
}
