huh? :)
After the poll(): the Comet servlet, in a tomcat thread will be able
to call
read() in the input
stream, and that will return data or 0 if no more data is available (
or -
call isReadable() and then read(),
or whatever else - but the socket will not be put in blocking mode ) ?
and some more huh :)
it is an implementation detail if the socket is blocking or non
blocking, and has nothing to do
with read() returning 0 or not.
now we are talking about the implementation, not the API. I can
implement inputstream.read() to return 0 on both blocking and non
blocking sockets.
btw, for the NIO connector, we only have non blocking sockets, the API
is an abstraction from the socket layer,
If this is true for sandbox - big +1.
not sure how the above relates to sandbox or trunk, since they use the
same sockets the same way.

It is non blocking, as the low level read is always non blocking (in the
sandbox design).
