You need to open a socket to the proxy server and send it an HTTP CONNECT request.
If the proxy server sends back an OK reply, then it has opened a socket to the proxy. After that the proxy acts as a port forwarder, so you can continue your SSL dialog with the proxy as if it was the SSL server. You should be able to Google the details.

The situation is like this: I have a client computer in a local network that is behind proxy server so it can not see a SSLServer directly. The SSL server is in Internet area. The type of proxy server is HTTP proxy. The task is a SSL data communication between local client and internet SSL-server. SSL port at the server is opened (without proxy). Of course, I'm using OpenSSL library. The SSL client trying to connect using "BIO_set_conn_hostname(bio, server_host_port)". Thus, I need to find appropriate functions in the OpenSSL library to setup proxy configuration for the client... or find other solution. 27.02.08, 12:32, "David Schwartz" <[EMAIL PROTECTED]>: > > 26.02.08, 23:23, [EMAIL PROTECTED]: > > > > > Hello, > > > > I have to connect to my OpenSSL server through proxy server. > > How can I > > > establish this connection? > > > Establish tcp connection through proxy (connect, socks5, > > > transparent, reverse or any other) and next run SSL on this tcp > > > connection. > > > Best regards, > > > -- > > > Marek Marcola <[EMAIL PROTECTED]> > > > > Thanks for the answer.
