Hello all, i have found the solution of Webpage has expired error when click on browser back navigation button when ever you can use session variable in your webpage that time this type of error is coming and mostly this type of error is coming in IE browser.
This issue is there with IE only not with Firefox and Chrome. In these two browsers getting the page correctly.
“webpage has expired” on back button PHP session problem:
You can setting the following in php.ini has solved this. 'session.cache_limiter=private' OR You can try this. working for all browser ini_set(�session.cache_limiter�, �must-revalidate�);
