Debugging a rule...

brandorr,

Well, from the described behavior, and the log entries there isn't enough information to give a definite answer.

I can certainly say it looks like your rule might have a couple of redirects that will force it to redirect again:

...
 redirect to "/hr"
...
} elseif { $my_uri == "/hr" } {
    redirect to "/HR/signon.html"
...

This kind of behavior will cause delays, as the request has to process through the complex rule multiple times before reaching its final destination.

That being said, to further diagnose the issue you're seeing, I'd recommend taking simultaneous, full tcpdumps on both interfaces of the BIG-IP to see what traffic is actually being passed from/to the client and the server. With this data you'll be able to see the request that the client machine is sending, and the exact response the BIG-IP is sending back. Hopefully this will paint a little bit more clear picture as to what's going on.

HTH,
