My understanding is, that some of the new hip and cool web programming techniques require the streaming hookup. So presumably the decision is: do we want Seaside to support those or not. The HTTP server can handle direct streaming of files (in both directions) without explicit streaming support in Seaside (if we avoid defeating it with things like WAFile>>contents). So it's not about handling large files. It's about being able to do new kinds of web programming. Assuming the decision is yes, we want streaming, then being able to either stream or not for any particular response should yield the best of both, and should suite most purposes. So I'm not sure what exactly is the argument here. Does the streaming hookup proposed here seem too complicated, compared to the benefits?
