Only placing the placeholder in the beginning works, anything else causes 301 redirect loop

Also placing the % somewhere in the middle breaks the functionality.

Works as expected for all cases now! Please review and test.

Works well!

I ran into the same problem. I can confirm that this little code change makes a prefix work as well as a suffix. I can't wait until this is merged! Thank you!

@serverjohn perhaps someone might want to ping the maintainer? Guess they are not aware of this.
