 // This StreamSocket implementation is to be used with servers that
 // accept connections on port 443 but don't really use SSL.  For
 // example, the Google Talk servers do this to bypass proxies.  (The
 // connection is upgraded to TLS as part of the XMPP negotiation, so
 // security is preserved.)  A "fake" SSL handshake is done immediately
 // after connection to fool proxies into thinking that this is a real
 // SSL connection.
