Handling Web Page has expired Issue ( IE 7.0) in ASP.NET 2.0

Question

Hi all,

Problem:

I have two aspx (ASP.NET 2.0)  pages 1) A.aspx and 2) B.aspx. If i navigate from A.aspx to B.aspx with the default values and click on the Browser Back Button then Page navigates back to A.aspx.

If I change some data in the A.aspx page and (if that page has postback) and navigate to B.aspx and click on the Browser Back Button I am getting the Message as "Web page has Expired" instead of navigating to the A.aspx. My requirement is to send it back to A.aspx.

I tried with the "Do not save encrypted pages to disk" option in the Security settings of the browser but still the problem persists. Is there any way get rid of this issue either through coding or through browser setting of through any fixes ?

Thanks & Regards,
