Does not allow redirects to IP addresses with port numbers associated. I have a docker container on a local server with a "GO F*CKING WORK" static page that I want to use instead of something with puppies or kittens.

Would otherwise be 4 stars since it does what it advertises on the tin, but not being able to use addresses with ports is lame.

Also, don't tell me to "put a proxy in front of it".
