CONNECT: Proxy Access to Secure Web Servers
When an http client wants to connect to an HTTPS server, but needs to do it through a proxy server, it issues a CONNECT to the proxy server. For example, the client connects to the proxy server and issues:
CONNECT www.onsale.com:443 HTTP/1.0 User-Agent: Mozilla/4.08 [en] (WinNT; U ;Nav)
And the server responds with:
HTTP/1.0 200 Connection established Proxy-agent: Apache/1.3.9 (Unix)
From there, all traffic is encrypted with SSL. The browser sends another HTTP message, this time inside the connection that was established with CONNECT through the proxy server. At this point, the proxy server just relays the data between the client and origin server.
