There are two ways of doing this:

1)  The application running over TCP.  In this case the HTTP 400 error
is telling you that the web server is done talking to you and no
future requests will be processed.

2) The other way is when you read, did you get an EOF error?  EOF =3D=3D
server has called shutdown() on the socket.

Ruby sockets behave just like C sockets.  It's just the Ruby language
wrapping them.  There's nothing "special" about ruby sockets.  What
this means is that the best resource isn't the ruby docs- they just
document the ruby API.  To understand how sockets work, read Richard
Stevens or start doing google searches on things like "tcp detecting
close".

The PSH (Push) flag has nothing to do with it.  PSH just tells the
receiving host that the TCP packet has interesting data for the
application and it should quickly "push it up" to the application for
processing.

Depends on what you mean by "all this stuff".  If you mean making TCP
a reliable, bi-directional stream & session based programming
construct then yes, the kernel does that for you.  If you mean dealing
with knowing when you can read/write to the socket, then no, that's
your job.  You the programmer have a lot of control over tcp sockets
and are expected to know how to use them properly.  As I said last
time, while TCP sockets utilize a very similar API as File IO, but
they are more complicated and you need to know how to use them.

Good luck.
