Your easiest and best bet would be to create a transfer page that will read the contents of the current session variable. Then, create a loop that puts down a hidden input field with the id as the name of the session variable, and the value as the session value. Put this within a form and post it to the page on the other application, then loop through and resintate the session variables on the other application.

It's actually quite easy.

Otherwise you will have to change statemodes while many other things.

you can use data base,
from the second application (after authentication has been done) you can query session variable from the browser and check the value of that data from data base.

Thanks DangerDev, sounds logical
