Re: [squid-users] Regex optimization

A small quantity of big regexes performs well. The CPU load is the same as if there's no regex at all. The thing I don't understand is why this specific regex matches every uri I throw at it in squid, but not in linux grep, or regex101.com. The generation of the big regexes takes seconds and is d
