Yeah, I think you're right. I'm not coming up with a better way to invalidate caches across multiple servers -- except maybe some kind of RPC, which would be real real losey.

Thanks! I thought about this, but forgot to put it in. I don't have a clever idea for how to do notifications for non-logged-in users with static files.

It's definitely a trade-off -- whether the performance advantage of serving static files would outweigh the loss of functionality from always generating dynamic pages.

In the long term when the system will get very busy should we generate a static page for apache to "include" with a module for the dynamic. So that it can be part cached and part live. Just thinking aloud :)
