exit_on_http_head WordPress Filter Hook
The exit_on_http_head hook allows a plugin to short-circuit the HTTP HEAD request method. This can be useful for cache plugins that need to quickly determine whether a page has changed before fetching it from the cache. It can also be used to prevent WordPress from loading unnecessary resources when all that is needed is the HTTP HEAD information.
