Temporary URL for an asynchronous API

Question

I am designing an asynchronous API according to the RESTful principles set out here. This involves a temporary URL, specified in the response's Location header, which clients can poll for status updates until their result is ready. I've never dealt with temporary URLs before, so how might I go about building one? We are using the Hunchentoot (Common Lisp) webserver.

Answer 1

I would not expect that URL to be temporary. That shows the status of the creation request. When creation is done, the response from that URL would indicate <status>done</status> or somesuch. If you really want to pull that URL (which I don't recommend), then you would return a 404.
