Fixed #10904 -- Corrected inappropriate usage of the term "absolute URL"...

Fixed #10904 -- Corrected inappropriate usage of the term "absolute URL" throughout the docs. Replaced with the (RFC 2396-compliant) terms "absolute path reference" or "absolute path" as appropriate for the context. Thanks to sharan666 for the report, and Malcolm, Chris, and dwillis for their work in supplying a solution and patch.
