Yes, it will stop Squid from caching these URLs while proxying them.

You don't really need to escape the / in regex patterns.

Well, this depends on what your hierarchy looks like. this is not related
to caching, only how Squid selects to forward the request within the
hierarchy of servers.

It is a plain string match, not a regex match.

hierarchy_stoplist is mostly the same as always_direct except that it is
slightly weaker (it won't override never_direct like always_direct does).
