C/C++ High efficiency sock reverse proxy

i have to write an high efficiency sock reverse proxy in C/C++, so i was wondering, is there any library/framework to easily handle sockets, proxying, etc just to focus on the main part of the project (not the proxy itself :)) ?

Something like the ACE framework but possibly i li开发者_如何学Gottle bit smaller and/or proxy oriented ...

Thanks

libevent is pretty good. ACE is horrible :)

Delegate is a good existing generic proxy tool. You should be able to fairly easily extend it for the protocol of interest.
