URL shortener troubles

[gerwitz]

I have a simple config that has been working well. Recently, Miro changed their URL shortener hostname from mandrillapp.com to mandrillapp.miro.com. So I updated my urlShorteners list.

I cannot get this to work!

If I use the new hostname in a handler, it is matched properly, but that does me no good because the only app I have to reconcile the redirect is Finicky itself. (Yes, I created an infinite loop by specifying Finicky :laughingstocks:)

I've tried rebuilding from a blank config with only this urlShortener as a standalone test, still to no avail.

What is magic about this hostname?
