 I believe these headers needs to be changed or removed. The Pragma: no-
 cache isn't an offical method of having no cache, and I think should be
 removed. Also, if HTTP/1.1 is being used, then Expires should be removed
 and Cache-Control left...There's some updating and optimization that can
 be done here.

 {{{
 function nocache_headers() {
 738         @ header('Expires: Wed, 11 Jan 1984 05:00:00 GMT');
 739         @ header('Last-Modified: ' . gmdate('D, d M Y H:i:s') . '
 GMT');
 740         @ header('Cache-Control: no-cache, must-revalidate, max-
 age=0');
 741         @ header('Pragma: no-cache');
 742     }
 }}}
