adding cookie cause page expire

Hi all

I want to communicate from one application to another application. Calling another application I am passing password through cookies. It is working fine.

The problem is back button. I am adding cookies in to response object while authenticating. After authentication, if I press back button browse shows page expired details.

What can I do?

the page expired is probably caused by you going back to a "POST" request. What you need to do is make sure that you go back to a "GET" request. You can do that by either changing the method of your login form to "GET", or do a redirect after you do the login.
