Is it possible to use app_offline with Azure Websites?
===

I connected to my Azure Website (reserved) via FTP this evening and uploaded an app_offline.htm file (tried HTML as well) but it isn't causing the application to stop as an app_offline.htm file would in a normal hosting environment.

Is it possible to do this on Azure Websites?

The site is a DotNetNuke site, but I doubt that has anything to do with it (as all of my other sites are based on DNN in normal hosting)
