[Eventletdev] Reverse proxy using eventlet

Hi!
I'm trying to develop a reverse proxy and was wondering whether eventlet
was a good option for it.
I've taken a look at proxylet, but it seems outdated.
I need the following features:
- SSL support on both sides of the reverse proxy
- One connecting user should connect to one server and stay at that
server. Other users should get other servers. I guess this implies some
type of session handling via some type of cookie, but I'm not sure.
Any hints/tips would be helpful.
