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