"~" means "this arg is a regex, not a string". "~*" means "and that regex
is case-insensitive". The rest of the argument is the regex; in that,
"^" means "match the start of the string".

So "~^GET/test" in this case will match all GET requests that start with
"/test". "~GET/test" would also match any requests that include the
8-character sting GET/test, which is probably not what you want.

Yes, the order is important. Per the docs: the first matching regex is
the regex that counts.

So - if you have some things which are subsets of some other things,
you must put the more specific ones earlier in the config list.

Good luck with it,
