The case._parse_url method was overly complex and merged several different pieces of functionality. This change extracts the part that creates a fully qualified url when the url is not already fully qualified. It also moves query_parameter extension to its own method. The resulting code is still complex (and has further changes forthcoming) but is moving in the right direction.
