title: Preventing strangers accessing WEBRTC pages
body: <p>I am creating a sample application to tryout <code>WEBRTC</code>. I came across a <a href="https://www.webrtc-experiment.com/meeting/" rel="nofollow">tutorial</a> that explains the process. I tried copying the code and it seems to work.</p>
  
  <p>Question is:</p>
  
  <p>I ONLY want a few people to access the page that containing the stream. How can i prevent other unauthorised users from accessing my page. A tutorial that walks through the process would be ideal.</p>
  
  <p>the language i am using to develop is <code>Grails</code>.</p>
