Expire page

[fotiss13]

Hi all,
i am quite new in php and i dont even know if this question has to do anything with php :) when i press the back button sometimes i get this message that the page has expired. Some other times it goes to the previos page without a prob. Anyone has an idea what message that means?
Thanx

Hi fotiss13,

this means you submitted a form via the method "POST".
if you use the "GET" method the values in the form will be shown in the url, but you are able to use the backbutton very easy. this is highly recommended for a search feature on your site.

It can also happen if the site uses sessions. If you're unsure as to what these are, try this [php.net]. Another possible, however unlikely, possibility are cookies.

HTH,

i do use sessions but it does not happen to all pages that have session. i guess its the thing with the post.
