We are using aspdotnetstorefront ML/64 version 8.0 for our main ecommerce site. Occasionally, some of our users complain that they are unable to logon to the site and the site keeps them redirecting to the main page every time they login. I traced it to the error in formsauthentication.decrypt method during authentication and it mainly happens on IE and usually due to a corrupted cookie. The error is
------------------------------------------------------------------------------
Exception message: Invalid value for 'encryptedTicket' parameter.
Stack trace: at System.Web.Security.FormsAuthentication.Decrypt(St ring encryptedTicket)
at AspDotNetStorefront.Global.rBU0jjPAT(Object , EventArgs )
---------------------------------------------------------------------------------
Usually clearing the cookie makes this issue go away. But is there a way to solve this issue without having the user manually deleting the cookie? This is really causing problem to our users and I am looking for a solution at the earliest. Any help in this regard is greatly appreciated.
