WordPress/wp-includes/template-loader.php
Mark Jaquith 08e68c1ec4 When receiving a HEAD request, die() right before we start outputting content.
* Content doesn't make sense for HEAD requests
* Saves wear and tear on the server
* Introduces a filter: exit_on_http_head (we send TRUE through it)

fixes #14348. props mbijon, mitchoyoshitaka.
