DescriptionRegular Expression matching follows the Unicode Technical Report #18: Unicode Regular Expression Guidelines. Unlike Perl based regexes (which are POSIX-based), the unicode regular expressions don't assume or try substrings by default. This means you have to craft a pattern that strictly matches the entire URL, supplying wildcards where you otherwise wouldn't in text editors that have their own regex engines.
Implicit Flags: All regexes use global flags.
/g : Global Search is always assumed and cannot be overridden.
/i : Case In-sensitive search is always assumed and cannot be overridden.
Example Regular Expression matches:
.*\.jpg$
- Match specific directory structure
^assets\/images\/.*
- Match on a specific hash in the middle of the URL, e.g. http://test.domain.com/b9805fca-b3a0-4ce0-9c21-ac7f482c1d06/r/img.gif
.*b9805fca\-b3a0\-4ce0\-9c21\-ac7f482c1d06.*
