the class LoginProxy method handleCallback.

/**
 * this is the method, which gets fired when the identity server returns back the authorization code, after
 * authenticating the user. in addition to the authorization code, the response from the identity server must also
 * include the state parameter, which contains the value we set when we initiate the authorization grant.
 *
 * @param code the authorization code generated by the identity server. the proxy application will exchange this
 *            token to get an access token from the identity server.
 * @param state this is the same value we set as state, when we initiate the authorization grant request to the
 *            identity server.
