Seems like when fired by Google Maps, MapServer doesn't return any Response Headers. If I take the same query and send it manually, I get the response headers, and I get a nice image back. Any idea what is going on? My guess is I am doing something wrong on the Gmaps side. Here is my relevant code var lyr = new google.maps.ImageMapType({ "getTileUrl" : function (tile, zoom) { return uri + "layers=" + name + "&mode=tile&tilemode=gmap&tile=" + tile.x + "+" + tile.y + "+" + zoom; }, "tileSize" : new google.maps.Size(256, 256), "isPng" : false, "opacity" : 0.5, "maxZoom" : 22, "minZoom" : 1, "alt" : "", "name" : name }); map.overlayMapTypes.push(lyr)_______________________________________________ mapserver-users mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/mapserver-users
