The `OpenID Connect Session Management 1.0 <https://openid.net/specs/openid-connect-session-1_0.html>`_ specification complements the core specification by defining how to monitor the End-User's login status at the OpenID Provider on an ongoing basis so that the Relying Party can log out an End-User who has logged out of the OpenID Provider.
An RP can notify the OP that the End-User has logged out of the site, and might want to log out of the OP as well. In this case, the RP, after having logged the End-User out of the RP, redirects the End-User's User Agent to the OP's logout endpoint URL.
This URL is normally obtained via the ``end_session_endpoint`` element of the OP's Discovery response.
Parameters that are passed as query parameters in the logout request:
*``id_token_hint``
Previously issued ID Token passed to the logout endpoint as a hint about the End-User's current authenticated session with the Client.
*``post_logout_redirect_uri``
URL to which the RP is requesting that the End-User's User Agent be redirected after a logout has been performed.
*``state``
OPTIONAL. Opaque value used by the RP to maintain state between the logout request and the callback to the endpoint specified by the ``post_logout_redirect_uri`` query parameter.
