I have the same ASP.NET application that is installed in two locations on the
same web server, each with it's own application in IIS. One instance is our
Intranet and uses Windows authentication, the other is our external website
and uses Forms authentication.
User's can log into each instance just fine, and as long as they only access
one of the applications everything works fine.
However, if a user logs into one application and then tries to access the
other without first closing their browser and restarting, they get the
following error...
Bad Data.
