The idea is to not lose time matching things you don't need. So, instead of matching the whole URI with `.*` or even a single character via `.?`, you can just match the beginning of the string `^` and be done with it.

In the second regex, I created a non-capturing group `(?:___)` since that first match is not being referenced anywhere.
