Thanks Gunnar and Mumia.
I figured out that the problem is unique to Internet Explorer. The three
other browsers I tried don't have this problem. But I can't get IE to not
cache. I've tried these:
print "Cache-Control: no-cache\n";
print "Pragma: no-cache\n"; # for HTTP/1.0
print "Expires: Fri, 26 Mar 2004 01:40:42 GMT\n";
print "Cache-Control: must-revalidate, max-age=1\n";
IE still caches.
Can anyone give some insight into where the problem might be?
Thanks.
