app_Offline.htm doesn't work for subfolders of my application in IIS

Question

I have placed an app_Offline.htm in the root of my IIS7 application. This works for calls to pages on the root, but not for calls to pages in a subfolder of the application.

How comes? And how to make it work also for subfolders?

Answer 1

The app_offline.htm is monitoring by asp.net only on the root directory of your web, or on any subfolder that is defined as application in iis.

So the answer is that is not work for subfolders and this is logically.
