+For a Drupal8 site offering a library of H5P (https://h5p.org) learning objects for external embedding, we need to override Drupal8's default X-Frame-Options header setting of "SAMEORIGIN" which prohibits embedding content. So, only in the case of H5P objects, which have a path starting with /h5p/[ID]/embed, we remove that header.
