I've got an external method that is generating a (possibly quite large) audio file and sending it back. Right now, I'm generating this in memory in a big string, then returning it to zope. I'd _like_ to be able to just have the external method send the data straight through (maybe in chunks) without having to read it all into memory. Is this possible with zope at all?
I think the first problem will be finding a publisher that streams. PCGI buffers all I/O, perhaps FastCGI doesn't. Even if you didn't, sending it through Zope in chunks would avoid getting Zope's memory footprint up there. One way would be to have the ExternalMethod return a sequence, then do something like: <!--#in myExtMeth--> <!--#var "RESPONSE.write(sequence_item)"--> <!--#/in--> Of course the above might be completely wrong, but you get the drift :^) --Paul
