OK thanks. I was hoping there would be a way to accomplish this with ISA. I sounds like there is no possible way to publish anything to the right of the FQDN, based on what you are saying.
I just told you how. You just have to accept the fact that you are not approaching it correctly,...and then approach it correctly. Then everything is fine. Your problem is not ISA and never was,...your problem is how you have the web server configured.
we were hoping that the users would not have to type in the long subsite name, and could just use an FQDN that would redirect to the subsite. [as it does internally and from the ISA server
Of course you can,..what I have been telling you gives you exactly that. I'm telling you that if you do it correctly then the user will not type in a long URL,...but rather a short FQDN.
