admin.php -> What does the header(‘X’) do?
header('Expires: Wed, 11 Jan 1984 05:00:00 GMT');
header('Last-Modified: ' . gmdate('D, d M Y H:i:s') . ' GMT');
header('Cache-Control: no-cache, must-revalidate, max-age=0');
What do these do? I had a problem with a plugin, and apparently these lines were causing trouble. If I edit them out, does it greatly affect anything?
Many thanks for your help.
