need suggestions for reverse proxy

[Haim Ashkenazi]

Hi

I'm looking for a reverse proxy for https to protect an IIS server. at the
moment I'm using "pound" but then the IIS doesn't recognize where the
original request came from so I can't do things like allow,deny from a
certain IP or use awstats. It should be able to deal with sessions and
load balancing (although at the moment I only have one server but I'll add
another one soon).

any suggestions?

thanx
