Re: JSP "Page has expired" Error

[Eric Fleming]

I have also encountered this problem and I am not sure how to solve it, please forward suggestions to me as well.   Eric   ----- Original Message ----- From: Jack Xu To: [EMAIL PROTECTED] Sent: Thursday, January 03, 2002 12:08 pm Subject: JSP "Page has expired" Error I need some help on this problem:   Consider the following scenario:   Two pages: page A, and page B. page A has a link to page B.   Page A uses: response.setHeader("Cache-Control","no-cache"); //HTTP 1.1 response.setHeader("Pragma","no-cache"); //HTTP 1.0 to expire the page once it is loaded in order to ensure the data display on the page A is up-to-date.   the problem happends when there is a self-posting form on page A. If a self-post in commited before linking to page B, and from page B, user clicks on brower-provided Back button, he/she will get a "page has expired" error. (it is not a big deal, since a simple refresh will solve it. However, it is still not preferable.)   Cause of the problem: form data expired. Only occurs on IE.   Any suggestions?   Thanks a lot. Jack
