Question

I have this JWT authorization configuration in my Startup.cs:

services.AddAuthentication(opts =>
{
    opts.DefaultAuthenticateScheme = JwtBearerDefaults.

Thanks for your suggestion... after spending a good time on google i could find your post and that worked for me. You raised a very good point because it does not make sense for app API calls.

However, I have a situation where the Actions called from the app has a specific notation route (/api/[Controller]/[Action]) which makes me possible to distinguish if my controller has been called by Browser or App.

app.UseStatusCodePages(async context =>
{            
    var request = context.HttpContext.Request;
    var response = context.HttpContext.Response;
    var path = request.Path.Value ?? "";

    if (response.StatusCode == (int)HttpStatusCode.Unauthorized && path.StartsWith("/api", StringComparison.InvariantCultureIgnoreCase))
    {
        response.Redirect("~/Account/Login");
    }
});
