To reply to my own post, I found that Netscape doesn't update all of its
display
cache even when I physically reset both memory and file caches via Prefs.
A reload of Netscape cleared up the non-showing of data on the output page
with the sequence Session_start/headers/session_register.
What is not happening is data tracking when using the browser back button.
Should I be caching the pages for, say, half an hour vs no caching?
header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
$expires = time() + 1800;
header("Expires: " . gmdate("D, d M Y H:i:s", $expires) . " GMT");
header("Cache-Control: max-age=1800");
This seems to work, but is there a cleaner way? Also, I can't find info on
conversion to my time, PST in the USA, but that shouldn't matter since I'm
not referring to it anywhere in the scripts.
Thanks for your help so far, Richard, Eugene, list, and any others I missed.
