A few thoughts:

 

  1. One of the most prevalent "reverse proxy problems" is when an application doesn't understand that it's behind a reverse proxy and either serves up object references (images, JavaScript, style sheets, etc.) and redirect URLs with HTTP:// when the VIP is listening on HTTPS://, or the application serves up (absolute) object references for the server name that it thinks it is, versus the host name represented at the VIP. The easiest way to pin this down is to run a client side capture and see what the server is sending through the proxy.

     

  2. Not nearly as likely, but still a possibility, there could be TCP-related (and/or possible HTTP profile settings) issues between the F5 and the server. Again, a capture is your best bet for troubleshooting this one.
