title: What is Push Initiator application URL field in BB6 application
body: <p>I am trying to enable BB push service in my PushDemo code i had taken from the BB sample code. But the Content provider URL is empty in the demo code . </p>
  
  <p>They are saying, If you use the BlackBerry Internet Service as the PPG, in the Push Initiator application URL field, type https://{server_address}/high-level-sample or https://{server_address}/low-level-sample.</p>
  
  <p>I didn't get what this URL is and what that "high-level-sample" or "low-level-sample" means.</p>
  
  <p>How can i do this ?</p>
