I am running ISA Enterprise in Mixed mode and have been experiencing problem with post and form submitals. Anytime I try to post toa site with any database behind it, I get "Page Cannot Be Displayed" "DNS Entry" etc. I have changed my DNS Servers to several of UUNEts root servers and still have the same problem. If I resubmit a form then it will work. How do you turn caching off for a individual URL? Any ohter ideas would be appreciated.
