That won't work. I solved the problem using javascript. Javascript doesn't cache like JSP pages does, so you can get around this problem using javascript.
If you want, I can send you the code I use.

Oops, I guess I should test before I post. It looks like newer browsers don't support this as a META tag only as a header.
I added the following to one of my action classes and the perform() method was called when I pressed 'Back':
response.addHeader("Pragma","no-cache"); response.addHeader("Cache-control","no-cache");
Hope it helps, Thane

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

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. -Original Message- From: Peter Alfors [mailto:[EMAIL PROTECTED]] Sent: Thursday, June 07, 2001 9:52 AM To: [EMAIL PROTECTED] Subject: Re: Can anyone help with solving the "BACK" button problem, in the browser? 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.
