Problem with a PACFILE VS

Okay, so let's say you have an HTTP URL configured in your browser. That URL points to an F5 VIP, and that F5 VIP load balances the pacfile servers. If you open the browser and only see traffic TO the VIP, but no return traffic, then there's a good chance the VIP itself is misconfigured. If you see return traffic, but none of it is the requested pacfile data, there's a good chance that either pool or pacfile servers are misconfigured. Do a packet capture on the server side of the proxy to see if there's any request and/or response traffic going to/from the pacfile servers.
