User editable layers at maps.google.com integrated into JavaScript v3 applications - how to refresh cache

[Bob Torzynski]

Greetings,

This question relates to embedding user-editable layers at maps.google.com into google maps javascript api v3 applications. 

In my application at: http://bike.zgroks.com/index.html, there is included a layer called as such:

rtEditLayer_url = "http://maps.google.com/maps/ms?msid=212925685488873680953.0004b6f5861b51720b824&msa=0&mid=1328716954&output=kml" ;

rtEditLayer = new google.maps.KmlLayer(rtEditLayer_url, {preserveViewport: true});

rtEditLayer.setMap(null); 

The code above calls a map at maps.google.com that is set to allow public collaboration.

When the user wants to edit the layer at maps.google.com, this function (below) is called:

function edit_map () { 

       var mcenter = map.getCenter();

          var mlat = mcenter.lat();

          var mlng = mcenter.lng();

          var z = map.getZoom();

          var myType = map.getMapTypeId();

          var goToLoc2 = 'https://maps.google.com/maps/ms?msid=212925685488873680953.0004c4ab35f55e7bc304e&msa=0&z='  + z + '&ll=' + mlat + ',' +mlng;

          window.open(goToLoc2);

         }

         

         

This all works well and good, but changes made at maps.google.com seem to take various amounts of time to propagate to the main map.

Is it possible to add a random query string parameter to the end of the variable goToLoc2 to cause maps.google.com to refresh the cache?

Any help, or examples linking to applications employing a similar functionality would be much appreciated.

Dont you mean rtEditLayer_url ? Ie it is displaying the content where
the caching is happening.


rtEditLayer_url = rtEditLayer_url + "&rnd=".(Math.Random());

Yes, I am trying to update the rtEditLayer. When changes are made via maps.google.com, they take some time to show up on the map at bike.zgroks.com ... I don't know if it's reasonable to expect the updates to show up right away, but the sooner that they showed up, the better. What I'm wondering is can I put a random parameter in the rtEditLayer_url when I call it through the edit_map function and if I do that will it affect anything (i.e., does maps.google.com cache the url)

yes Google caches the data ...
