When using ArcGIS Online basemaps in the JavaScript API, for example:new esri.layers.ArcGISTiledMapServiceLayer("http://services.arcgisonline.com/ArcGIS/rest/services/World_Topo_Map/MapServer");
An invalid MIME type is returned from the arcgis online server. Using Chrome Developer Tools, the following warning is returned for every tile request:Resource interpreted as Image but transferred with MIME type image/jpg: "http://services.arcgisonline.com/ArcGIS/rest/services/World_Topo_Map/MapServer/tile/8/100/75".
I believe the proper MIME type for any sort of JPEG/JPG image should be "image/jpeg", not "image/jpg". Most browsers should be smart enough to interpret the image correctly, however it's quite annoying to see these warnings stack up in the JavaScript console.Has anyone else experienced this issue?
