I saw in debug log that when an ACL has many regexes each one is
compared sequentially.
If I have
www.facebook.com <http://www.facebook.com>
facebook.com <http://facebook.com>
www.google.com <http://www.google.com>
google.com <http://google.com>
If will be faster to check just ONE optimized regex like
(www\.)?(facebook|google).com than the previous three?
I'm really talking about optimizing about 3000 url regexes in one huge
regex because comparing each and every url to 3000 regexes is too slow.
I know using
(www\.facebook\.com)|(facebook\.com)|(www\.google\.com)|(google\.com)
with PCRE will produce the same optimized result as
(www\.)?(facebook|google)\.com. Squid uses GnuRegex. Does GNURegex lib
optimizes this as well ?
