Excuse me, by "packet" I meant IP datagram. See, there's a router in the
path that splits my POST into two IP datagrams, one containing the http
header and one contining the http payload (an xml message). It also adds
a "connection:close: header. Apparently splitting the http message and
adding "connection:close" cause Tomcat to send non-chunked.

BTW, Tomcat also doesn't send a content-length header, so if it's not
chunked I don't know how long the message is.
