Most efficient way to search for upper case in [HTTP::uri] or [HTTP::path]

I think the most efficient way to do this is to use the matches_glob operand (replacing the 'contains' in your example above). Still, I'm not quite sure how [A-Z] will match any upper-case character.

You could use matches_regex but there's higher overhead I believe. Still, if you can't get the glob to work it might be necessary, I think the regex would look like: [A-Z]+
