Hi all, I have a rather serious problem ? and can?t think of any way to solve it. I have a cache hierarchy with TWO cache boxes running on different internet links at the core, then 10 regional cache?s peering to the top. The reason I say two, is because one link is for a specific set of users, and the other is for normal users. These ?business? users need to go through the regional cache?s and out the ?business? link ? but I?m not transparently caching so they are actually pointing at the regional cache. My thinking was that I could use cache_peer_access and use a different port for business users on the regional cache?s ? changing their setup is not a problem. However, cache_peer_access port specification only works with the destination port, and if they are pointing to me on say 3129 but going to google.com:80 it wont pick it up? So I need a way to maintain (through multiple cache?s) a business users state and have those sessions go out the one peer at the top. Does anyone know of a way to do that? If not, I?ll have to task someone to ?modify? the cache_peer_access ? or something else? What would be the best place to look? Thanks Dave
