@zaggino that's a good idea.
Technically you can already use regex to test for a match by setting origin to a function, but I think that directly assigning a regex will make the code concise and easier to understand.
I suggest to also add an option to assign an array to origin to support an origin whitelist.
Supporting regex and array will mean that you hardly never need to use the function syntax (the only reason to use it will be for complex scenarios).
@troygoode, what do you think?
