Feature Request: Delegate to HTTP for get/post

[womblep]

My scenario needs me to call HTTP requests as well as the SSE.
I need to do a post to authenticate to get a cookie which the SSE request would use.
Once that is listening, I need to send posts to trigger events to come via SSE (one post might generate 1 or X events depending on the function)

If the SSE engine could delegate HTTP requests like the SocketIO engine does, that would solve the issue.
