Asanka,
The exact timing of the remote side closing the connection shouldn't matter. If
coded propertly, buffers are flushed before/on close. The TCP FIN sequence will
be queued *after* all the data packets. So the data will remain within the TCP
stack and is not lost, even if the client starts reading long after the
connection has been closed. A packet dump (Wireshark) should give us more
information here.

Hi All
When talking over SSL to a BEA WLI server, it responds with a
"Connection: close" header, and seems to close the socket, before Apache
Synapse (using HttpCore/NIO) could read the full message (~11K in size).
Its setting the 'Content-length' header, but when debugging the SSL
communication, we see that the full reply never reaches the client.

Is this something possible when using "Connection: close" ? and if so,
what can a client do to prevent loosing the reply
thanks
