By default, ASP.NET will issue a 302 redirect to the error handler. You can change that by setting the redirectMode to ResponseRewrite:

XML

<customErrors mode="On" redirectMode="ResponseRewrite">
    <error redirect="~/Error/Error401" statusCode="401" />
    <error redirect="~/Error/Error403" statusCode="403" />
    <error redirect="~/Error/Error404" statusCode="404" />
    <error redirect="~/Error/Error500" statusCode="500" />
</customErrors>

NB: Make sure your error handler sets the appropriate status code on the response, otherwise all errors could return a status of 200.
