　　Good point. But some feedback here. The optimail syntax is:

　　<?php

　　// process form

　　// ...

　　// redirect to results page

　　header('Status: 303 See Other' );

　　header('Location: http://www.glzy8.com/result.html');

　　?>

　　Here's why...

　　Using "Status:" in the header is better because the resulting headers from

　　Apache are more correct:

　　HTTP/1.1 303 See Other

　　instead of

　　HTTP/1.1 303

　　Additionally, one doesn't really know which version of HTTP is being used,

　　so why potentially cause problems by trying to guess.

　　The specs say location headers must have a complete URI in them, not just

　　the path.

　　Lastly, you don't want any output after the location header.
