Thanks for the suggestion, I’m looking into this. The thought that I have is to do this convention based. So if you have a file named app_offline-template.htm then we use that file for app_offline.htm. Please let me know if that design doesn’t work for you.Ken Kick commented
Anything more on this? After searching all day, I found your 2012 comment in the IIS forum that this was removed due to a security issue, but that you guys would work to put back in. Now 4 years later...??
