A guess is that the site is using session cookies with embedded source IP information. Try setting "prefer_direct off" in squid.conf. This will make it more insisting in using parents even when doing so makes no sense from a caching perspective. You can also use never_direct to force Squid hard to go via peers. And cache_peer_access to limit which peers. Both these allows you to tune for this site only if you like. Alternatively try using always_direct for the site to not go via peers at all, which also accomplishes the same goal of having a single source IP for the session. Regards Henrik
