I tried two ways to send 404 message to browser:
1£ºheader("Status: 404 Not Found");
2£ºheader ("http/1.0 404 Not Found");//from php manual
Both of them do not work:
the browser do not show anything, just like show "about blank" page.
But it work if I use it to redirect browser:
header ("Location: http://www.php.net").
So I am in trouble. Can you help me?
