twisted web write to a connection closed from client-side
Hi, I have a problem: twisted does not indicate/throw exception when user has stopped reading the stream via "STOP" browser button (I guess it won't do in any other case of connection drop). Is this intended behavior and is there any way to detect that the data written to request goes nowhere? I am using twisted web to write HTTP stream that is read form asynchronous source continuously. I'm using Resource and NOT_READY_YET, then I just do request.write() infinitely until, and if, the source stops the stream, then do request.finish(). If the source does not stop and I stop the stream by hitting browser "stop" button - the twisted server continues reading source infinitely. Could not find any information about how connection resets are handled by twisted web

Shouldn't the HTTP protocol implementation (twisted.web.http) itself respond to connectionLost?

It does. What else do you think it should do? Jean-Paul
Jean-Paul, thank you for your reply, I got it working great.
Anyways I suggest to indicate it somehow more clearly in the Request
documentation because Deferred interface is far from trivial.
Jean, and for your great post- could you please extend your post title
to contain "connection drop" or variants to be easier to find it via
google. You're doing great work with your "twisted in 60 seconds",
many thanks again.
