I do a lot of local dev and my local DNN urls have a port number. After installing Url Master everythign looked good, even the test URL came back with a 200/OK, but after applying the changes I couldn't reach any URLs (either by the new rewritten paths or the original paths).
After digging a bit, I "reverted" by replacing the adjusted web.config with the ver prior to applying the changes from the Url Master which got me back to having the module installed, but not actively rewriting URLs (note: you might think about having an "enabled" flag on your provider's tag in web.config so a noob like me could just switch it off without reverting the whole config, which I was only probably convinced wouldn't botch anything else
) .
I've gone through the process (and reverted) a couple of times now and I don't see what I'm missing. Does it usually work ok with URLs with port numbers?
Appreciation in advance! Cheers, Jeff
