That is a specific behaviour of that page, or better scripts on that
address. For example new versions of IRC servers check if you are not
conecting from open proxy by connecthing back to your IP and scanning for
SOCKS/HTTP proxies on some standard ports.
Scripts on page you are trying to get probably do the same. May I know
what is exact address of that page, to see what's happening?

I don't think this is related to squid. This is imho problem of the page
you are requesting and scripts on it. This imho does NOT belong to SQUID
FAQ, but probably to remote server's or page FAQ.

I see that it was already added to the SQUID FAQ. I'd like to investigate
this problem a bit more...
