You have a redirector somewhere down the chain between your web server and
the client browser, which is re-writing the PATH segment of the URI with
the full URL. Probably due to an old transparency bug fixed months ago.

You will need to track down the squid operator and yell loudly at them to
fix their proxy. The footer of the error page which gave you squid/2.6
should have the machine name of the squid just before the version.
An rDNS and whois lookup should give you the company name and contacts.

You will probably find its the visitors ISP doing traffic control.

Meanwhile. You can break the infinite loop with a URL test at your end. It
might be a good idea to mention the issue in a custom error message so the
visitor can yell at their ISP as well.
