This is not correct regex syntax for the given URL, and why have you left
out the protocol part? You should also bind the pattern to start/end of
line.

It is mainly ., ? and + you need to escape as these have special meaning
in regex. There is also a few other special characters but these is not
very often seen in URLs. There is no need to escape the / as / is just /
and nothing special.

Complete list of special characters in regex: ^.[]$()|*+?{}\

See

man 7 regex

for a in-depth description of the regex language. Squid uses what is known
as "Modern/Extended" regex, not the old style regex syntax.
