Intercept Unauthenticated request with Windows Authentication

I have an ASP.NET Core MVC application with Windows authentication enabled, and I want to use a basic interceptor to handle unauthenticated requests, but it is totally skipped because the Windows authentication mechanism blocks the request before entering the interceptor.

Do you know if there is a way to bypass this standard behaviour not blocking the request going in the interceptor pipeline?

Thanks in advance!

Use a middleware and declare it before the UseAuthorization

public class YourMiddleware
{
    private readonly RequestDelegate _next;

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

    public async Task Invoke(HttpContext context)
    {
        Console.WriteLine("Before");
// Here you can decide if you want the next step of the pipeline or not, usually you want
        await _next(context);
    }
}

app.UseMiddleware<YourMiddleware>();
app.UseAuthorization();
