I have a split dns with the internal network dns server returning the internal ip address of our web server and the internet registered domain returning the external ip address which is published through an ISA server. The IE8 client connection settings use the proxy server (ISA) and I have added the domain to the list of exceptions in IE8 to bypass the proxy server. The IE8 host returns the internal ip address of the web server using NSLOOKUP but IE8 still requests the page using the proxy server. I can see this happen by monitoring the proxy server. Since I have added this domain to the Exceptions it should request the page directly from the web server but it does not. Is there a trick to making IE8 bypass the proxy server?
