title: Google Cast Receiver Applications
body: <p>In the receiver developer's guide is the following:</p>
  
  <blockquote>
    <p>Applications running on the Google Cast receiver device (receiver applications) are always web applications. They are launched on the device after it receives instructions from the sender application to do so.</p>
  </blockquote>
  
  <p>How exactly is this accomplished from the sender (in Chrome)? The sender guide doesn't seem to include this anywhere and I'm unable to track down it down in the API docs.</p>
  
  <p>There is the class cast.LaunchRequest, but there isn't anything there that would accept a receiver application URL.</p>
