Thanks for the responses. This is a great forum!
One last Q. In Apache I would use a MOD__REWRITE to rewrite the URI. In IIS I would use ISAPI_REWRITES to rewrite.
I see how I can redirect (which gives a 302 in the header). I would like to proxy a request in F5. This is how it was explained to me:
"You use a proxy when you want to control processing of the call from the point you receive it, and forward. A proxy can see the provisional and final responses to the request. It can record route so that it sees whats going on during the call. A redirect, however, hands off control to the device that sent. It will never see the final response to the request, and not be contacted again for the remainder of the call. Its a one-shot deal."
