More info about that "subsequent request" -- it is a history.back() javascript call. But as I said, that fails when we use squid (goes into an infinite loop), but works fine when we use a different proxy (such as Apache mod_proxy or CCproxy) which sends HTTP/1.1 headers. Trying IE7 isn't an option for us right now, so we're discussing internally whether we can fix this with code or if we need to switch to a different proxy. It looks like IE6 is misbehaving here, but there doesn't seem to be a way to fix it.
