We have a setup where we publish a website from behind ISA. The websites rely heavily on active server pages. Since we put the web server behind ISA, some clients are receiving partial pages returned when they post a form. This never occurred prior. The interesting thing is the page (not all pages) returned suddenly starts spitting out malformed html code rather than the formatted page i.e.: (<fontface='arial' siz) then quits. No error message on the page. Not only that, the end of the page is not always in the same place although close, and twice, the whole page was returned. We have been unable to duplicate the error on any of our computers either behind another isa, or straight out to the internet. Only by visiting one of the clients where we able to see this error firsthand. Both clients with the error are behind another firewall which I have not as yet learned the details of. Any thoughts on what direction I should look to resolve this? Thanx Bob Cheeseman
