Dear All,
In a Windows Server 2008 (64bit), there is an IIS. Under the default web site, there aretwo asp.net 4.0 applications (Application A and B) using Forms Authentication.
Each application has unique machine key.
However, on a browser with different tab, when having signed in to application A, application B is automatically signed off. When sign in to application B again, application A is signed off. The signing are mutual exclusion.
How to solve this?
