F5 10 LTM APM with XenApp CloudGateway

You can use the same setup/guide for load-balancing Citrix Web Interface for 10.2.x from f5.com and apply it to the StoreFront servers. Citrix officially does not document how to perform SSL offload on the StoreFront servers, although it is possible - even though you setup your StoreFront servers as https, they are listening on port 80 as well - so you CAN perform SSL offload for them if you choose to do that - it'll save you off a few CPU cycles in the grand scheme of things. Else, you can easily just load-balance and either use source IP address as persistence or decrypt/re-encrypt on the BIG-IP in order to use cookie persistence.
