A SAML Single Logout (SLO) response follows the typical SAML message structure, with an ID and information about the message’s origin and destination.
The logout response also includes the ID of the original SAML logout message, which the IdP or SP can use to correlate responses with original requests to confirm that the response was intended for it.
The logout response also contains a status code, which indicates whether SLO failed or completed successfully or partially.
