I think it's a matter of definitions: I'd call it forward proxy already if client decides what services to connect to, and proxy server is specified on it as, well, proxy. In any case, it does not matter much how you call it. In your case you'll need rather simple rewrite rule that changes URLs of all requests from http to https, with P option, and that's all. It is hard to say more without doing experiments. -- With Best Regards, Marat Khalili
