I was testing a form on Netscape 4.x and kept getting the error:-
” 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. ”
after trawling a few lists I noticed this post [link removed] mentioning that there might be a problem with the “expires” header.
I then removed from my HTML Meta tags this line:-
<meta http-equiv=”pragma” content=”no-cache” />
and that seemed to fix it – I also changed the expires tag to 15 rather than -1
