Nope, that is just a bug in Netscape where it doesn't
pay attention to the server closing the connection.

It can never gain any performance advantage out of
behaving in this manner.  It should always notice when
the server closes its half of the connection, and complete
the close.  The server isn't going to accept any more
requests on that half closed connection, and even if it
did then it couldn't send any responses.

See a document that I think I mostly wrote a long time ago
that talks about this:


(yes, it is an old document that hasn't been updated in a long time)
