<div dir="ltr"><font face="Arial" size="2">My project is considering GeoRSS as our data-sharing standard with partners. I am pleased with how easily OpenLayers will display GeoRSS points, but I'm wondering how other developers ensure efficient auto-updates. My first impression was that OpenLayers would automatically check a GeoRSS XML file and automatically load updates (i.e., like an RSS aggregator). </font><font face="Arial" size="2">When further exploring, it seems like custom code must be written to auto-update the layer. </font></div>

<div dir="ltr"><font face="Arial" size="2">Am I missing something? Is there a way to ensure new points added to a GeoRSS file are automatically, efficiently loaded by OpenLayers (without page refresh)? It seems like there must be a better way to update the layer than destroying and reloading the GeoRSS layer.</font></div>
