title: Does the HTML5 Geolocation protocol work with just GPS connection enabled?
body: <p>Here's a hypothesis: </p>
  
  <ul>
  <li>A simple web app based on the HTML5 Geolocation feature has a button "Get my location" that when clicked, will display the latitude and longitude of the client.</li>
  <li>The client accessing the app has GPS enabled, as well as a live data connection to the internet</li>
  <li>The client accesses the application, then once its loaded, the connection to the internet is severed; the client device GPS is still enabled and working</li>
  </ul>
  
  <p>Question: will clicking the button still return the position of the client based on just the GPS input data? Or would an HTTP request need to precede that somehow?</p>
