public static function DomainRedirectResponse::externalIsRegistered in Domain Access 8

Determines if an external URL points to this domain-aware installation.

This method replaces the logic in Drupal\Component\Utility\UrlHelper::externalIsLocal(). Since that class is not directly extendable, we have to replace it.

Parameters

string $url: A string containing an external URL, such as "http://example.com/foo".

string $base_url: The base URL string to check against, such as "http://example.com/".

Return value

bool TRUE if the URL has the same domain and base path.

Throws

\InvalidArgumentException Exception thrown when $url is not fully qualified.

    // partial URL match isn't occurring. Since base_path() always returns
    // with a trailing slash, we don't need to add the trailing slash here.
