Good point! The "server" part of Squid is probably violating (if not the

The FYI part is very misleading: It is possible to handle URLs correctly
(without caching problems and DoS vulnerabilities) while preserving URLs
(in general cases). It is not easy, but it is certainly doable. Also,
URL preservation is not driven by QA. Some might argue that it is
necessary for real-world compatibility; it is essentially a design
choice, not a QA requirement.
