Can ISA be run as a proxy, similar to a hardware caching server. I would like to implement ISA similar to the caching hardware solution we currently have. Do not need any firewall features, just looking for a caching server that requires no client or AD GPO setup. Is it possible to run ISA without the policy etc. Would like to just set our router to redirect http to ISA server. If anyone knows whether this is possible or not please let me know. JT
