I have set up a custom authorization failure page and configured it under Failure URL for my Authorization policy. It's working fine as a replacement for the canned OAM operational error page. However I'd like to include a "retry login" link on the failure page that links back to the original requested URL. Is there any way to get the original requested URL from such a custom AuthZ failure page? I tried setting up some Responses (Header type) in the AuthZ policy, but they aren't appearing on the HTTP request for the failure page.
