I don't think it's productive to go over this all again because I've done it several times over the last few months. Nevertheless, recognize that you are arguing not with the HTTP specification but with one of Tim Berners Lee's Web Axioms. The HTTP specification is just a reflection of those axioms. Here are some references: * http://www.w3.org/DesignIssues/Axioms.html * http://lists.w3.org/Archives/Public/www-tag/2002Feb/0091.html * http://lists.w3.org/Archives/Public/www-tag/2002Jan/0182.html * http://www.xml.com/pub/a/2002/02/06/rest.html * http://www.ebuilt.com/fielding/pubs/dissertation/rest_arch_style.htm * http://www.ebuilt.com/fielding/pubs/dissertation/evaluation.htm This isn't an HTTP issue. It is a web architecture issue. Paul Prescod
