HTTP Streaming: what realizations of Push Technology are available?

I'm currently in search of an usable re开发者_如何学Goalizations of http Push Technology. At least it must support channel subscription and channel publication.

What convenient implementations in C++ (or C) are available?

Only thing that comes to mind (in C++) that supports server push and self contains a httpd is Wt. It's actually remarkably easy to get installed, compile a program, and get running. I didn't have any Qt background. If you do that will make it even easier for you.
