Description:
Shepherd: Jonathan Rees

At the TAG F2F of 4 March 2009 (http://www.w3.org/2001/tag/2009/03/04-minutes#item03), the TAG agreed to "split Issue-57 into two issues as edited by NM, with one abstension DanC".  Issue 62 was opened immediate.  Later issue 63 was opened.

At their meeting in 16th July 2007 [1] the TAG resolved to create a new issue, HttpRedirections-57 as a response to a community request [2] that we give further consideration to the use of the HTTP 303 status codes *and* other possible mechanisms of obtaining a description of a resource (typically a non-information resource) where the referenced resource is not capable of providing representations of itself.

Particular concerns are the cachability (or otherwise) of HTTP redirection responses (see email from Roy Fielding [3] indicating presense of a bug in the specs); UI confusion where redirection leds to changes in browser address-bar content and questions of the practical bookmarkability of a reference in the presence of a redirections.

Related notes:

2007-09-10 00:00:00: In a SWIG IRC discussion http://chatlogs.planetrdf.com/swig/2007-09-10#T01-48-20 it was noticed that a finding would be useful here on what base URI should be used fro parsing documents which have been redirected. It seemed clear that after a 303 See also or a 301 Moved redirection, the seocnd URI should be the base, However one could argue that after a 302 Found redirection, the baseshould b the original (stable, eg a pul) URI.
