This succinct suggestion for adding support to asynchronous responses came from Roberto De Almeida (roberto at

My suggestion would be to return a 202 Accepted ( response with a "Location:" header pointing to a unique URL. Accessing the new URL should return either a 404 Not found if the response is not ready; 200 OK if it is; and 410 Gone if it has been generated and deleted after some time.

Comment: jimg 18:47, 22 January 2009 (PST) This effectively factors the issue out of DAP and says that how asynchrony will be handled is dependent on the transport protocol. I think that's essentially correct. For example, SOAP has an asynchronous mode and DAP over SOAP should use that, not some DAP-specific hack.
