  Key Concepts: 
  Relay state is a parameter used in the SAML protocol to identify the target URL of a service provider. It is used to redirect the user back to the service provider after authentication. The relay state parameter is sent along with the authentication request from the service provider to the identity provider. 
  
  How to use it: 
  The relay state parameter is used by the identity provider to redirect the user back to the service provider after authentication. The service provider must include the relay state parameter in its authentication request and set it to the URL of the page that should be displayed after successful authentication. 
  
  Tips & Tricks: 
  When using relay state, make sure that it is set to a valid URL and that it is properly encoded. Additionally, make sure that the URL is secure and does not contain any sensitive information.
