Minor Description
ExternalUrlResourceReference allows using a url as a resource reference. Currently, the class requires that the url be absolute. I couldn't find a reason for this restriction and my tests show the class works without it.
This issue is to remove the absoluteness restriction for the url. This will allow referencing resources on the same server root as Wicket, but which are not managed by Wicket.
