<font style="font-family: arial,helvetica,sans-serif;" size="2">Hi all,<br><br>I found an entry in a Google Code FAQ (<a href="http://code.google.com/support/bin/answer.py?answer=69906&topic=11367#displaying">http://code.google.com/support/bin/answer.py?answer=69906&topic=11367#displaying</a>) showing how to use MySQL to create KML files which can be loaded into Google Earth or Google Maps. The thing that interests me is the following:</font><br style="font-family: arial,helvetica,sans-serif;">
<br style="font-family: arial,helvetica,sans-serif;"><pre class="code"><font style="font-family: arial,helvetica,sans-serif;" size="2"><?xml version='1.0' encoding='UTF-8'?><br><kml xmlns = '<a href="http://earth.google.com/kml/2.1">http://earth.google.com/kml/2.1</a>'><br>
<Folder><br> <NetworkLink><br> <Link><br> <href><a href="http://example.com/phpsql_genkml.kml">http://example.com/phpsql_genkml.kml</a></href><br> <refreshMode>onInterval</refreshMode><br>

<refreshMode>onInterval</refreshMode><br> <refreshInterval>3600</refreshInterval><br> </Link><br> </NetworkLink><br> </Folder><br></kml></font><br style="font-family: arial,helvetica,sans-serif;">
<br style="font-family: arial,helvetica,sans-serif;"><font style="font-family: arial,helvetica,sans-serif;" size="2">This indicates that the KML files are automatically reloaded by Google Maps every 3600 seconds. It looks like refreshMode and refreshInterval are part of the KML specification. Does OpenLayers support this auto refresh functionality?</font><br>
