None really. Just make sure the sticky bit is enabled and that you use a least connections method of balancing. Also make sure the session timeout isn't smaller than your Mid Tier timeout.
There are some occasional issues with the AR Server not allowing a user to login because they're already logged in from another machine. This seems to happen if a user connects through Mid Tier and gets routed to server A, then closes the browser without logging off (or they can even try to logoff but Mid Tier doesn't actually log them off). If they then try it again within 15 minutes and the load balancer (seeing a brand new connection) routes them to server B, then AR Server will prevent the login because it thinks they're still logged in from server A. We don't have too many issues with this, but then most of our users are on Remedy User. Sometimes when the issue happens a lot we reboot the web servers and it seems to correct itself. I'm hoping this is handled better in 7.1.

They are currently running Mid Tier 6.3 patch 20 on IIS/ServletExec and are about to be rebuilt for Apache/Tomcat. But all the load balancing is done through the BigIP, not through IIS. We have a 60 minute timeout with session affinity (sticky bit) enabled and balancing based on least connections.

But we were told by support to route all traffic from http to https using rewrite commands in apache. Then, the ip stickiness on the https load balancer works. I don't like the solution.
