print "Content-type: text/html\n";
print "Pragma: no-cache\n"; #This is for proxy systems only
print "Cache-control: no-cache\n"; #I think this is what you want
print "Expires: Mon, 06 May 1996 04:57:00 GMT\n";
print "\n"; #end header
I strongly recommend to everyone who does CGIs or anything mre than HTML to
get "Webmaster in a Nutshell" from ORA (http://www.ora.com/). This is all
in the section on HTTP headers.
You might find the same info online; do a search for "HTTP near headers".
