Major Description
When the client sends to the TS a CONNECT request for ssl termination connection, and we r trying to send this request to upstream proxy, then the TS removing the CONNECT header and connecting to the upstream server.
For a case we want to send to the upstream server the CONNECT header, I wrote an API and attached the patch for this.
the idea is to raise a special flag for this connection that the TS will know that we want to pass the header as it is.
This one is good especially for transparent connections.
