Reverse Proxy XenApp

I'm guessing, because you're talking about "Juniper SSL", that you're also referring to APM in terms of SSL VPN? If so, I would argue that while you could serve these (static) files from the F5, you shouldn't have to, or probably wouldn't really want to, considering that APM can do all of this for you natively. APM provides an ICA proxy capability, the ability to look up users in an AD, and redirect client connections where necessary. With APM, you can also completely remove the Access Gateway, STA, and Web interface from a Citrix environment.

 

 

If you could elaborate on how the process currently works (what the headers and JavaScript files are actually doing), it'll be easier to help with an alternative mechanism. Otherwise, take a look at the following thread that discusses serving files from iRules: https://devcentral.f5.com/community/group/aft/2166695/asg/50.
