RE: Can anyone help with solving the "BACK" button problem, in th e browser?

I seem to recall a META tag called something like pragma-no-cache that you
can embed in your page which will force the page to reload (not just display
a snapshot). This should enable handling the situation in scriptlets or your
action class.

Depending on which browser you use, and the data on the page, the back
button
may cause (or ask) the page to reload.
However, some browsers (like IE) only display a snapshot of what the last
page
rendered to.
Therefore, you cannot use scriptlets or the action class.  However, you are
able
to kick-off javascript.
If you can gaurantee that your users will have javascript enabled, you can
write
a simple test to see if this page was already displayed to the user.  You
could
check a flag (hidden field) when the page loads.  If the flag is true, then
use
the javascript to reload to your desired page.

Thane ,

I am using:
    <META http-equiv="Expires" content="now">
in my header, and my action is not re-executed when I use the browser
back button.
Is there another option I should be using?

thanks,
    Pete
