19 * An oauth2 redirection endpoint which can be used for an application:
20 * http://tools.ietf.org/html/draft-ietf-oauth-v2-26#section-3.1.2
21 *
22 * This is used because some oauth servers will not allow a redirect urls
23 * with get params (like repository callback) and that needs to be called
24 * using the state param.
