Answer 1

Using the ASP.NET Web Optimization Framework

Easier way to do it when you're using bundles.

Get the Microsoft.AspNet.Web.Optimization package from NuGet. Now in your BundleConfig you can setup your bundles to include not only the CdnPath, but also a CdnFallbackExpression:

public static void RegisterBundles(BundleCollection bundles)
{
    bundles.UseCdn = true;
    BundleTable.EnableOptimizations = true;     
    var jquery = new ScriptBundle("~/bundles/jquery", "//ajax.aspnetcdn.com/ajax/jquery/jquery-2.0.0.min.js").Include(
            "~/Scripts/jquery-{version}.js");
    jquery.CdnFallbackExpression = "window.jQuery";
    bundles.Add(jquery);
    //...
}
