Warning: Page has Expired

[aamchi mumbai]

Hi

I have a report page which show list of item. User can click on item and see detail page.
But now if user click browser back button i am getting warning page saying that
Warning: Page has Expired The page you requested was created using information you submitted in a form. This page is no longer available. As a security precaution, Internet Explorer does not automatically resubmit your information for you.

is there any way to display previous list page? if i change post method to "GET" it is working but i dont want to do that.

Thanks in Advance

This is one of the consequences of instructing the browser not to cache the page. I expect somewhere in your page you have something similar to the following:

<%
 // Instruct the browser not to cache the page
response.setHeader("Cache-Control","no-cache");
response.setHeader("Pragma","no-cache");
response.setDateHeader ("Expires", 0);
%>

When the user hits the back button, the browser gets the page from it's cache: it doesn't go to the server. One way to avoid this message would be to allow the browser to cache the page, but that might cause other unwanted side effects. Many websites simply accept this message, and hope users will learn not to use the back button. Go to your online banking website, and chances are you'll get this message if you hit the back button. One solution is to use javaScript to disable the back button.

Good luck.

also, check the controller property in your struts-config.xml. if you have the property 'nocache' sets to 'true' for the controller, that will also cause the expired post.
