If you want to close a http server with only one request from a
brower ,
send 'Connection: close' header to client for ending the connection.
To be more safe, setting maxConnections = 1 is best to avoid
concurrent
connections as below.
I noticed that doing 'req.connection.destroy()' would also end the
connection. What is the difference? Is this second option also
notifying the client of the imminent closing of the connection, or is
it just abruptly closing the socket connection?
Node checks 'Connection: close' header. If it exists,
socket.destroySoon() is called after 'finish' event so that a write
buffer is surly cleared at the time when a connection is closed while
'req.connection.destroy()' just closes it in regardless of the write buffer.

Note: The 'finish' event and socket.destroySoon() are not public APIs.
Do not use them in your program.
