Hi,

In that case you might need to use to make it work.

BundleTable.Bundles.UseCdn = true;

Please try. Hope it helps to solve the issue.

That's was a quick reply! Thanks!

Sorry to give some perspective, this is what I already have:

    public class Bootstrapper : IApplicationEventHandler
{
    public static void RegisterBundles(BundleCollection bundles)
    {

    }

    public void OnApplicationInitialized(UmbracoApplicationBase umbracoApplication, ApplicationContext applicationContext)
    {

    }

    public void OnApplicationStarting(UmbracoApplicationBase umbracoApplication, ApplicationContext applicationContext)
    {
        BundleTable.Bundles.UseCdn = true;

        var jqueryCdnPath = @"//ajax.aspnetcdn.com/ajax/jQuery/jquery-3.4.1.min.js";
        var jqueryBundle = new ScriptBundle("~/Content/bundles/jquery", jqueryCdnPath).Include("~/Scripts/jquery-3.4.1.js");
        BundleTable.Bundles.Add(jqueryBundle);
    }

    public void OnApplicationStarted(UmbracoApplicationBase umbracoApplication, ApplicationContext applicationContext)
    {

    }
}

The switch works fine but the fallback doesn't. I'm not sure if I have to perform a separate check in the master template or if this is automated? I've spotted this on Microsoft Docs: https://docs.microsoft.com/en-us/aspnet/mvc/overview/performance/bundling-and-minification#code-try-6 but this makes me wonder why we include the local path in the script bundle?

I've cracked it. Just couldn't spot it. I had an 'add trailing slash' rule applied which was causing my fallback to fail.

<add input="{REQUEST_URI}" pattern="^/umbraco/*" negate="true" />
<add input="{REQUEST_URI}" pattern="^/bundles/*" negate="true" />

I already had an negation for /umbraco so just added one for my bundles path and it worked.

is working on a reply...
