communicating with web service via SSL via proxy server

I am attempting to communicate with a web service using SSL i.e. port 443 via a proxy server. I can create a socket and open a connection to the proxy server but I can't then communicate via SSL using OpenSSL using the created socket connection. Has anyone managed to do this on here, and if so could they please guide me in the right direction.

Many thanks.
