Hi Phil, Since you discuss HTTP status codes and their definitions, I just wanted to point out that the current drafts of HTTPbis (i.e. the upcoming revision of the HTTP spec) include a definition[1] for 303 specifically tailored to the way it's used in LD today.
(There was also a long, philosophical thread[2] on www-tag some time ago where the merits and shortcomings of this change were heavily debated.)
