title: Make Google Maps retain zoom and center after refresh?
body: <p>How do I make Google Maps retain the user's view (zoom level and 
  center point) after an HTTP refresh? </p>
  
  <p>Right now, it resets the view after each refresh. Can I tweak the code 
  below to say "zoom: current zoom level" and "center: current center 
  location" somehow? </p>
  
  <pre><code>function initialize() {  
    var myLatLng = new google.maps.LatLng(0,0);  
    var myOptions = {  
      zoom: 2,  
      center: myLatLng,  
      mapTypeId: google.maps.MapTypeId.TERRAIN  
    };  
  </code></pre>
  
  <p>I have figured out some other ways to do this for

  considerably harder. </p>
