This was discussed on the mailing list a while back -- "load balancing" or something was the subject.
With your current setup, you'll do better to have a third server (or dual use for one of your current servers), and have it redirect people round-robin-style to www1.whatever, www2.whatever, etc. Then users will always go back to the same computer for their session. This is what you want, but round-robin DNS won't ensure they always go back to the same server. I don't know if mod_rewrite has a randomizing thing in it -- I'd be surprised if it didn't -- so you could probably implement this as a single rewrite rule. A fairly simple extension to the adapters has been suggested, where an adapter would do the load balancing for you. But that's not implemented.
