Ahh,
it seems that the tiles are being loaded, but no data. That would
explain something.
Of course loading the tiles based on the current scrolling position
would not be a security issue.
Ok, well I will have to spend some more time to read about this, can
you please explain on thing :
what is the difference between :
new OpenLayers.Layer.GML("OSM", "file.osm", {format: OpenLayers.Format.OSM});
and what I was trying to do that did not work :
new OpenLayers.Layer.Vector("Lines", {
strategies: [new OpenLayers.Strategy.Fixed()],
minZoomLevel: 1,
maxZoomLevel: 6 ,
numZoomLevels: 5,
protocol: new OpenLayers.Protocol.HTTP({
url: "test-embed_files/testway.xml",
format: new OpenLayers.Format.OSM(),
})
});
Thanks,
mike
