For my application I need fine-grained control over the ciphers used when establishing the TLS sockets underlying the outgoing HTTPS connection. This functionality is supported by the HTTPS client using the ciphers parameter:
http://nodejs.org/api/https.html#https_https_request_options_callback
However, I couldn't find a way to use the parameter in the backend of a proxy, hence this pull request.
While I was in there I thought I'd add all of the other optional HTTPS parameters, so this pull request also passes pfx, key, passphrase, cert, ca and secureProtocol.
