When using the ASP.NET Script Bundles, you can provide the CDN locations where your script library can be found. When you also add the code locally you get the benefit of being able to debug against the non-minified version while the CDN version will be used when the site runs in production.

See the following documentation on setting up script bundles on ASP.NET Web Forms.

basically you need to add a couple of lines to the Global.asax:

void Application_Start(object sender, EventArgs e)
{
    BundleConfig.RegisterBundles(BundleTable.Bundles);
}

And then create your bundle as follows:

public static void RegisterBundles(BundleCollection bundles)
{
    //bundles.Add(new ScriptBundle("~/bundles/jquery").Include(
    //            "~/Scripts/jquery-{version}.js"));

    bundles.UseCdn = true;   //enable CDN support

    //add link to jquery on the CDN
    var jqueryCdnPath = "http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.7.1.min.js";

    bundles.Add(new ScriptBundle("~/bundles/jquery",
                jqueryCdnPath).Include(
                "~/Scripts/jquery-{version}.js"));

    // Code removed for clarity.
}

And reference it like this:

        
     <%: Scripts.Render("~/bundles/modernizr") %>
     <%: Scripts.Render("~/bundles/jquery") %>
     <%: Scripts.Render("~/bundles/jqueryui") %>

This should please both the browser and the editor.

You can also configure the to automatically fall back to the CDN using the following pieces of code:

And this configuration:

var mapping = ScriptManager.ScriptResourceMapping;
// Map jquery definition to the Google CDN
mapping.AddDefinition("jquery", new ScriptResourceDefinition
{
    Path = "~/Scripts/jquery-2.0.0.min.js",
    DebugPath = "~/Scripts/jquery-2.0.0.js",
    CdnPath = "http://ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js",
    CdnDebugPath = "https://ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.js",
    CdnSupportsSecureConnection = true,
    LoadSuccessExpression = "window.jQuery"
});

// Map jquery ui definition to the Google CDN
mapping.AddDefinition("jquery.ui.combined", new ScriptResourceDefinition
{
    Path = "~/Scripts/jquery-ui-1.10.2.min.js",
    DebugPath = "~/Scripts/jquery-ui-1.10.2.js",
    CdnPath = "http://ajax.googleapis.com/ajax/libs/jqueryui/1.10.2/jquery-ui.min.js",
    CdnDebugPath = "http://ajax.googleapis.com/ajax/libs/jqueryui/1.10.2/jquery-ui.js",
    CdnSupportsSecureConnection = true,
    LoadSuccessExpression = "window.jQuery && window.jQuery.ui && window.jQuery.ui.version === '1.10.2'"
});
