Agreed. This has been discussed in the WG before (can't remember the ref); basically, it boiled down to each request being independent; you don't want requests affecting other ones (beyond anything, it's a security issue if you allow clients to purge your cache indescriminantly). -- Mark Nottingham m...@yahoo-inc.com
