I noticed my ASP.NET app that I migrated from another host was showing JavaScript errors when opening the page editor, even though it didn't show this on the other host and the codebase was the same.
After doing some digging I noticed references in the markup to webresource.axd. I wasn't sure what this was at first but it turns out it's a the dummy file ASP.NET uses to refer to scripts it generates through a HTTP handler.
A Google search showed up lots of people having the same problem and all sorts of technical reasons for why it doesn't work.
I logged a support ticket and was amazed to see it was fixed within the hour! I was almost expecting a message saying "sorry that's not something we can fix" after dealing with other hosts.
Well done and thanks for resolving the one thing that stopped my
website hosting going live.
