title: Back-channel logout using OIDC
body: <p>I'm currently working on Backchannel logout using openid. The flow , as I have understood goes like the following</p>
  
  <p>1- User agent(browser in my case) triggers the logout using a link to the OP.<br>
  2- OP deletes the user sessions, and send the loogout token to the RP.<br>
  3- RP deletes all user sessions.</p>
  
  <p>Can somebody please tell me how to get the link to OP from the browser to trigger the request in the first place. I am using angular 4 on the front end if that matters.</p>
