If you are using a (generic) HTTP server to receive the request, you could set, in the httpc request, the User-Agent HTTP header to a known value and then extract the vaue of the User-Agent HTTP header at your server. Another option would be to set a cookie from the server to client upon first connection, and then send the cookie on all subsequent requests from httpc. 

Depending on what HTTP server technology you're using, there may also be other mechanisms available. What HTTP server are you using?
