If the form changes the state on the server, ie inserts something to the db, you should not output html but instead redirect to another page. Then Back button does not go to the post page but to the form page.

Hello,
I have a series of forms set over a few pages. The entries are stored
in session vars and the whole shebang is written to mySQL via PHP at the
end of the series of forms. When the user hits the back button an error
message comes up with the following
Warning: Page has Expired The page you requested was created using information you submitted in a
form. This page is no longer available. As a security precaution,
Internet Explorer does not automatically resubmit your information for
you.


To resubmit your information and view this Web page, click the Refresh
button. Is there any way to avoid this from happening?
Thx
