Chris, Squid will do this if you use a redirector and shuffle based-upon client request IP address. You would have to write a custom redirector that kept track of IPaddr to server-node mappings, and returned the right backend url. I realize this isn't perfect, but it should accomplish fair balancing of load and still keep sessions going to the server that first served them, assuming someone's DHCP lease doesn't get renewed or something like that. Alternatively for sessions, you could consider using an alternate storage served by your ZSS. So far, we have had good luck for our classifieds site's clipping application using the old BDB2 storage served over ZEO 1.0 with an old version of Zope using CoreSessionTracking, and I suppose this would likely work for Zope 2.5+ seasoning as well. It is quite likely that once packing is implemented in DirectoryStorage's "Minimal" non-undo storage (pack releases space used by deleted objects), we will use that for our newer applications as a session store.

Pound is a load-balancing server that apparently was built orginally specifically to feed traffic through Zope clients on a ZEO. I installed a copy and the setup is really really easy, but I haven't tried putting some stress on it to see how it works. We're using a squid-to-ZEO deal right now which works OK, but I need a way to bind a user to a server for sessions because we had real problems trying to use Berkeley to back a non-undoing storage for the built-in sessions. I got it working, but it looked like it was eating our servers for lunch. Now I'm not so sure that was what was causing our performance problems.
