Website gives a white page instead of an 404 error

Question

I have this quite strange problem:

When I go to a URL which doesn't exist on my website, it simply shows a white page. The Application_Error event is never run, and the user is not transfered to the 404 page we use.

I need to catch the Application_Error event, to do some logging and also some redirects.

I don't have access to the IIS, as I run my website on a shared webhotel. But with all my other websites this works fine.

Here is my web.config:

<?xml version="1.0"?>

        </rule>
      </rules>
    </rewrite>
  </system.webServer>
</configuration>

Any ideas? Thanks :-D

Set your custom errors to:

<customErrors mode="RemoteOnly" defaultRedirect="ErrorPage.aspx">
  <error statusCode="404" redirect="404-Error.aspx"/>
</customErrors>
