Hi there,

Yes, it is possible using Session variables, but remember that session variables are only availble in server side script, not client side script.

Add some server side script on the login page to check for the error variable set in the server script of the asp page that finds the error. The simple response.redirect just reloads the login.asp page, but this time the error variable exists, and it can process it appropriately.
