Hi,
I am wondering, for all the PHP files I've written, if I clicked on the "back" button on the browser, it will show:
"Data Missing
This document resulted from a POST operation and has expired from the cache. If
you wish you can repost the form data to recreate the document by pressing the
reload button. "
However, many PHP sites don't have this kind of problem ... Can anyone teach me
how to fix this?
Thanks.
