What information does the 'Relaystate' parameter contain in sp-Initiated Single Sign-on?

The ‘Relaystate’ parameter is an HTTP parameter that can be included as part of the SAML request and SAML response. In an SP-initiated sign-in flow, the SP can set the RelayState parameter in the SAML request with additional information about the request,such as the URL of the resource that the user is trying to access. The IDP should just relay it back in the SAML response without any modification or inspection. Therefore, the ‘Relaystate’ parameter contains a reference to a URL redirect parameter at theservice provider123.
