title: Is there a way with Spring Security to cache token introspection result?
body: <p>I have a Spring boot REST API protected by Keycloak with Spring Security.</p>
  
  <p>I can't find if there is a way to prevent token introspection on every request (i.e. caching introspection result for a short period). Everytime I hit the API, token is checked upon Keycloak and this is not great for performance :(</p>
  
  <p>Thanks for any advice.</p>
