title: apereo CAS to Angular/Spring boot application
body: <p>I am developing an application using Angular6 for frontend and spring boot for backend.</p>
  
  <p>Currently what I have is a frontend application that calls my spring boot APIs. At the moment all APIs are available to everyone for example localhost:8080/api/get_data</p>
  
  <p>Now I have to implement authentication using APEREO CAS protocol <a href="https://www.apereo.org/projects/cas" rel="nofollow noreferrer">https://www.apereo.org/projects/cas</a> If I am understanding correctly I'd have to check every API request if it contains some session cookie where authentitacion is stored... I'm a bit lost so any help is really appreciated</p>
