This should be straight-forward, but I am beating my head over it. KML will not display. I have tried from same server and remote server to ensure it is not a cross-domain issue. The KML file loads into Google Earth okay. However, kmlcsv Convertor generates an error saying it cannot read the kml. I suspect the KML has something"advanced" in it, any KML gurus there can look and tell me whether it is the KML or my code?
OpenLayers Code
typhoon = new OpenLayers.Layer.Vector("typhoon",
{
strategies: [new OpenLayers.Strategy.Fixed()],
protocol: new OpenLayers.Protocol.HTTP
({
url: "http://xxx.ph/kmz/storm-track.KML",
// url: "/storm-track.KML",
format: new OpenLayers.Format.KML
({
extractStyles: true,
extractAttributes: true,
maxDepth: 10
})
}),
eventListeners: {
"loadstart": layerLoadStart,
"loadend": layerLoadEnd
},
visibility: false
});
map.addLayers([typhoon]);

Best Answer
Ok, I have it solved, for future users here was the issue
I thought my cross domain was working ok as the browser sent a preflight to the third party server which returned the following
In fact, this was just the Preflight Request, Openlayers never issued the GET
When I moved the file to IIS on my server, I just woke up that there was no mime type defined for kml/kmz by default because Firefox was issuing the following in the console
Quite a bit of head scratching until I realized it was trying to interpret the file as a html file.
Added Mme Types as follows to IIS
Voila, I can see the kml now.
Thanks to all who helped ..
