Setting favico sitewide

[weirdyang]

What's the cleanest way to ensure the favico is consistent sitewide?

I'm currently using AdminBranding.cshtml but it doesn't replace the favico for all layouts, eg. the admin login page. Besides reimplementing the layouts and views, is there a way to ensure the same favico is used site wide?

I've also tried using a middleware, and although it is invoked, and the Redirect line is hit, the icon is stil served from TheAdmin/favicon.ico

    public class FaviconMiddleware
    {
        private readonly RequestDelegate _next;

        public FaviconMiddleware(RequestDelegate next)
        {
            _next = next;
        }

        public async Task InvokeAsync(HttpContext context)
        {
            if(!context.Request.Path.HasValue || !context.Request.Path.ToString().Contains("favicon.ico", StringComparison.OrdinalIgnoreCase))
            {
                await _next(context);
                return;
            }

            context.Response.Redirect("~/CustomModule/favicon.png");
        }
    }

    public class FaviconMiddleware
    {
        private readonly RequestDelegate _next;

        public FaviconMiddleware(RequestDelegate next)
        {
            _next = next;
        }

        public async Task InvokeAsync(HttpContext context)
        {
            if(!context.Request.Path.HasValue || !context.Request.Path.ToString().Contains("favicon.ico", StringComparison.OrdinalIgnoreCase))
            {
                await _next(context);
                return;
            }

            context.Response.Redirect("/CustomModule/myfavicon.ico", true);
        }
    }

needed to set redirect permenant to true.
