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,
