Hi All, I need to use different login forms for different folders with forms authentication. So i am using different web.config for each folder. Now if i write authentication tag in any sub folder's web.config it shows this error. (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.) I need it urgent, can u help. Thanks in advance.
