Daily Learning – Adding a global filter for authorization in ASP.NET Core

First, let me say that we love IdentityServer4.  It doesn’t hurt that we have been using IdentityServer since its early days or that Brock Allen is a good friend of ours.  We are doing some IdentityServer work for our customers and I needed to create a sample application that requires authentication for all pages.  After some digging around, I found that we can add a global filter for authorization.  Neat!
