When I click "Back" button from the browser, I get following message:-

"Warning: Page as expired."
How can I cache it.

Thanks

If you want to cache a form, specify OutputCache parameter as top, similar to the @Page directive. Look in MSDN for details.

bmains-
I tried that and then it does not even display fields on my form.
I also tried Response.Cachecontrol="Public", did not seem to cache it.
Then, I changed the form posting method from "post" to "get" on my login page and it seems to have increased the expiry duration a little bit, but does not completely go away. I have surfed the web for the same and found that this is something that I have to live with, IE has introduced it as a security feature. But, if you do have a suggestion, I can definitely try it, otherwise I will assume it that that's how the websites are.

Try setting the Response.Expires attribute.
