wp_page_reload_on_back_button_js

WordPress Version: 4.6

/**
 * Outputs JS that reloads the page if the user navigated to it with the Back or Forward button.
 *
 * Used on the Edit Post and Add New Post screens. Needed to ensure the page is not loaded from browser cache,
 * so the post title and editor content are the last saved versions. Ideally this script should run first in the head.
 *
 * @since 4.6.0
