Subject: [PATCH] Fix intercepted request string matching

- Use Ruby case matching semantics for intercepted request URL patterns so exact string patterns are compared literally instead of being treated as regexps.
- This preserves regexps matching while fixing blacklist and whitelist patterns containing regex metacharacters such as query string question marks.
