I have a main directory with many aspx pages created in VB.net.
I have a sub-directory with the backend aspx pages. I want to protect these pages with forms authentication.
(I want to implement form authentication in the sub folder only)

In my subdirectory, I have just added web.config file and getting following error.



Parser Error Message: It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level. This error can be caused by a virtual directory not being configured as an application in IIS.

Take a look at the ASP.NET configuration settings schema:

http://msdn.microsoft.com/library/en...tionschema.asp

Look at the "location" node. The default web.config does not have this node. However, you can create a whole additional <system.web> configuration section for a second location. This way you could define forms authentication for the "sub-directory/" path. This leaves the authentication node in the main application web.config so you don't get the error you posted.

You can use this same technique to make one particular path NON authenticated if you have an entire application that uses some form of authentication.
