Question

On Friday I gave a demo of an MVC application using the Authorize attribute on my JobCardController, and all was well. This morning, when I attempt an unauthorized action, I still get redirected to the LogOn view, using the below URL, but I appear to have what my reading tells me is called a White Screen of Death, i.e. nothing but white background and no actions invoked.

http://localhost:34054/Account/LogOn?ReturnUrl=%2fJobCard

ADDENDUM:
I forgot to mention that I have moved the Account models and services out into my DataObjects and Services projects, but I had done this last week already without this problem.

I’m not asking what is wrong, but what are the common faults that could cause something like this and how can I start debugging this mess?

SOLVED:
Somehow an Authorize attribute had landed up on my whole controller class, as in,

[HandleError]
[Authorize]
public class AccountController : BaseController

I removed that and everything is working again.

Answer 1

Somehow an Authorize attribute had landed up on my whole AccountController class, as in,

[HandleError]
[Authorize]
public class AccountController : BaseController

So, the controller was being repeatedly hit by an unauthenticated user for the same action invocation. I’m surprised this didn’t cause some sort of ‘stack overflow’ condition.
