 * Authorization Endpoint
 *
 *     The authorization endpoint is used to interact with the resource
 * owner and obtain an authorization grant.  The authorization server
 * MUST first verify the identity of the resource owner.  The way in
 * which the authorization server authenticates the resource owner
 * (e.g., username and password login, session cookies) is beyond the
 * scope of this specification.
 *
 * The means through which the client obtains the location of the
 * authorization endpoint are beyond the scope of this specification,
 * but the location is typically provided in the service documentation.
 *
 * The endpoint URI MAY include an "application/x-www-form-urlencoded"
 * formatted (per Appendix B) query component ([RFC3986] Section 3.4),
 * which MUST be retained when adding additional query parameters.  The
 * endpoint URI MUST NOT include a fragment component.
 *
 * Since requests to the authorization endpoint result in user
 * authentication and the transmission of clear-text credentials (in the
 * HTTP response), the authorization server MUST require the use of TLS
 * as described in Section 1.6 when sending requests to the
 * authorization endpoint.
 *
 * The authorization server MUST support the use of the HTTP "GET"
 * method [RFC2616] for the authorization endpoint and MAY support the
 * use of the "POST" method as well.
 *
 * Parameters sent without a value MUST be treated as if they were
 * omitted from the request.  The authorization server MUST ignore
 * unrecognized request parameters.  Request and response parameters
 * MUST NOT be included more than once.

Did you maybe forget this after debugging? Sometimes obsolete code just ends up commented out instead of removed. In this case it is better to remove the code once you have checked you do not need it. The code might also have been commented out for debugging purposes. In this case it is vital that someone uncomments it again or your project may behave in very unexpected ways in production. This check looks for comments that seem to be mostly valid code and reports them. Loading history...
