Oh, crap, I did it again.
WordPress core will send headers that prevent caching by browsers and RFC-compliant reverse proxies (like Ledge) when a user is logged in, or an error (such as 404) is returned. These headers are defined in wp-includes/functions.php:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 |
999 /** 1000 * Get the header information to prevent caching. 1001 * 1002 * The several different headers cover the different ways cache prevention 1003 * is handled by different browsers 1004 * 1005 * @since 2.8.0 1006 * 1007 * @return array The associative array of header names and field values. 1008 */ 1009 function wp_get_nocache_headers() { 1010 $headers = array( 1011 'Expires' => 'Wed, 11 Jan 1984 05:00:00 GMT', 1012 'Cache-Control' => 'no-cache, must-revalidate, max-age=0', 1013 'Pragma' => 'no-cache', 1014 ); |
Nothing crazy. But what’s so special about January 11, 1984? Beats me, I wasn’t alive then. But we have the Internet (and copious amounts of free time while I’m stuck on a graveyard rotation)!
