Heh. I hate the ACE gui mode. I think I used it once...

L2 load balancing is a big plus for us. We are currently using the ACE with inline mode (L2 bridging). Most of our traffic is not
HTTP, but a combination of internal application and commercial ones (Exchange, etc...), so some HTTP, but not a majority.
