[Erlyaws-list] Howto detect client connection close while streaming with stream_chunk_deliver?

[Stefan H. <hel...@gm...>]

Hello,

I would like to know the recommended way to detect when the client
disconnects from an HTTP streaming session. I am currently using
yaws_api:stream_chunk_deliver analogous to the first example given on
http://yaws.hyber.org/stream.yaws. It is just that my stream is
infinite (not finite as in the example given) thus the server will
read content and stream it forever or until the client terminates the
connection.

By looking at the API however I do not see any easy way to detect when
the client terminates the connection, thus my process will continue to
loop and do stream_chunk_deliver forever, making my yaws machine
slower and slower over time.

I have looked into older posts on this mailing list and I see that
there was a similar discussion around 2005 which discussed
possibilities of detecting yaws-process dying by spawn_linking the
streaming process. I have tried this however and it does not seem to
work for me. I do not get any message passed to me when the client
disconnects.

Anyone who has any idea on how to do this in an elegant way? Any example code?

Regards,
Stefan
