ok, thanks! And it's even smart enough to rotate on connection failure.
That's very nice to know about.

It was squid-2.6.STABLE6-5.el5_1.3 on RHEL5.

Thanks for the pointer, but that's not what we're trying to do no. It's
a webserver cluster, with shared filesystem (GPFS), and heartbeath
(linux-ha.org) for failover ip-addresses which are distributed trough
rr-dns. So, no squid on our side, but the users might be going trough
proxies, so it's important to test that everything works there too.

Turned out that our problem with browser looping over elements in the
webpage happens if a user is autenticated on the webpage, and switches
from proxied to non-proxied, or non-proxied to proxied connection. So I
guess it's a problem with the php-sessions maybe incorporating the
client ip-address in some cookies, and getting confused if the client ip
changes. So it was not a problem with squid in any way.
