Cascade Server currently allows for root-relative URLs to be published out when “Maintain absolute links” is checked. It would be very helpful at times if a page could have fully qualified absolute URLs. Currently this is almost possible by applying an XSLT to the page at the template level but will not work if there are External Link assets that are generated in region(s) of the page.
This may tie to feature requests regarding having Cascade gain a concept of a “site.”
