Just an update to keep things current:

In newer versions of Squid (1.1.11 is the one I'm looking at now),
REG_ICASE can be ORed into the flags variable by calling
aclParseRegexList() with the second argument set to 1 instead of the
default of 0. The calls are made in aclParseAclLine() which is found in

It would be very easy to add an option so that you could specify
url_regex/i instead of url_regex, but that doesn't seem to be in the code
yet. If anyone is still interested in this, I would be happy to provide
patches directly or to Duane.
