Returns an array of URL hosts which are considered to be internal hosts.
By default the list of internal hosts is comprised of the host name of the site's home_url() (as parsed by wp_parse_url()). This list is used when determining if a specified URL is a link to a page on the site itself or a link offsite (to an external host). This is used, for example, when determining if the "nofollow" attribute should be applied to a link.Related Functions: wp_insert_post, wp_initial_constants, wp_untrash_post, wp_write_post, wp_trash_post
