During a [presentation] I gave yesterday about REST, there was a discussion about redirection (more detailed, a redirection from a queue to the actual resource during [asynchronous operations)]. During this presentation (and blog-post), I’m using a [303 HTTP status code] to indicate that the operation has been completed and that the created resource can be found at another URI. So in essence, it makes sense to use a 303. At least to me, and quite possibly the rest of the world too.. But this triggered a side-discussion on which HTTP status code to use, and the more I think about it, the more complex it believe this problem actually is.
