A #SoupClientContext provides additional information about the client making a particular request. In particular, you can use soup_client_context_get_auth_domain() and soup_client_context_get_auth_user() to determine if HTTP authentication was used successfully.

soup_client_context_get_remote_address() and/or soup_client_context_get_host() can be used to get information for logging or debugging purposes. soup_client_context_get_gsocket() may also be of use in some situations (eg, tracking when multiple requests are made on the same connection).
