I get �Page has expired� warning when I use JavaScript
code �window.history.back()�.
Here is the problem instance. All our JSP pages are
not cached. We have the following scriplet code in our
JSP pages :
response.setHeader( �Cache-Control�, �no-cache� );
response.setDateHeader( �Expires�, 0 );
response.setHeader( �Pragma�, �No-cache� );
We�ve a JSP page that shows a input form. Enter some
invalid data and submit to a servlet. ( FORM action
is POST ). Error JSP page is displayed. Click on �go
back� button on the error page. The link to the �go
back� button is �javascript:window.history.back()�.
This causes the �Page has expired� warning page.
If I make that particular form JSP page cached, that
is comment the above lines, I get the form page with
previously entered values when I hit the �go back�
button.
Is there any solution to go back to the form page
without getting the warning page and without making
that form JSP page cached, when I hit �go back� button
on the error page?
Any help would be greatly appreciated.
Thank you.
