But it would seem that server A did not have them cached. It may be that these responses use Vary: header. ICP does not handle that type of response properly. You may get better behaviour using HTCP instead of ICP between the siblings. I also note that you have 40GB of RAM allocated to each of these Squid instances. Do you actually have over 100GB of RAM on those machines (*excluding* swap space)? Amos
