We are building an exchange cluster with two front end Outlook Web
Access servers. We would like to at least have some sort of failover, and prefereably load balancing for them.

Russ, take a look at

Yes, that what I was thinking. However, I believe these servers also run smtp, pop3, imap,etc, so I don't think Apache can handle all of those..
LVS handles all protocols. It can do any port and UDP or TCP. It supports different types of balancing Round Robin (rr), Weighted Round Robin (wrr), Least Connections (lc), Weighted Least Connections (wlc). It can do sticky sessions, so if OWA doesn't like when you go from server 1 to server 2, LVS will keep the user stuck to one server. Plus a ton of other features. Give it a shot.
