Hi All, I'd be grateful for any clarification on the following: - I have a dual homed ISA server installed in integrated mode which I now need to consider using, for caching purposes, as being downstream to a very large WAN-based caching server complex (I understand it to use ICP). Can this be done? If so, what do I need to do? If I have too, I would cease the caching function of my ISA server and organise things to use the VL Cache ICP driven distributed cache service on the WAN - however, I don't know how to. This stuff is all political so don't look for good sense or logic in my statement of problem. Me? - I'd like to keep my caching as local to my LAN users as is possible. Can I use, say, active caching with ISA to take feeds from the upstream ICP based VL Cache arrangements? Thanks in advance for any input on the above. DaveW
