Running vB on a load balanced web server setup?

[jwocky]

Ok, I have a site on a DB and web server combo which is running great, but I will have to upgrade to a 2 web server setup with a load balancer inbetween then and was asking on vb.com about this since I don't quite understand how this actually works and was hoping for some help...

Basicly, if I add a second web server with a load balancer, do I have to setup some kind of replication between the two servers to keep the web files instantly up to date between the two computers, or does the load balancer somehow use the hardware resources of the second computer without me having to setup any kind of replication between the servers?

Also eva from vb.com mentioned that I might have to do some kind of custom vb file hacks to make a vB forum work under a 2 web server enviroment.

Any tips or clues on how to do this and any conceptual help in understanding all this would be greatly apprecaited!!
