=item authenticate $c, $realm, \%auth_info
Tries to authenticate the user, and if that fails calls
Array reference to domains used to build the authorization headers.
+This list of domains defines the protection space. If a domain URI is an
+absolute path (starts with /), it is relative to the root URL of the server being accessed.
+An absolute URI in this list may refer to a different server than the one being accessed.
+
+The client will use this list to determine the set of URIs for which the same authentication
+information may be sent.
+
+If this is omitted or its value is empty, the client will assume that the
+protection space consists of all URIs on the responding server.
+
+Therefore, if your application is not hosted at the root of this domain, and you want to
+prevent the authentication credentials for this application being sent to any other applications.
+then you should use the I<use_uri_for> configuration option, and pass a domain of I</>.
