I already know (1) and (2). Actually in this two cases we don't need to do stream by ourselves. Recently I am trying to use web2py to develop a "desktop app", which need to stream files in anywhere on local hard disk. So not in range of (1) or (2), and even (3) is misleading in this case.
So, add one more stream example please. :-) On Apr6, 0:13am, mdipierro <[email protected]> wrote: > Now I understand better.
