problem with sockets code

[Daniel]

Hello,

I can't seem to get my sockets code to work right.  Here is what I
have inside my RequestHandler handle() function:

        total_data=[]

        data = True
        logger_server.debug(self.__class__.__name__ + ' set data =
True')
        while data:
            logger_server.debug(self.__class__.__name__ + ' receive
first readline() of data')
            data = self.rfile.readline().strip()
            logger_server.debug(self.__class__.__name__ + ' first
readline() of data = %s' % data)
            total_data.append(data)
        receivedCommand = '\n'.join(total_data)

And this is what I have inside my client code

    sock=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
    sock.connect(('localhost',5001))

    sock.sendall('Hello, world\r\n')
    data = sock.recv(1024)
    sock.close()
    print 'Received', repr(data)

There's a little more to it, but this is enough for me to ask my
question.  The problem is that  I can't get the server loop (while
data:) to stop without closing the connection, but I want to receive
something back from the server before closing the sockets connection.
My logs show that the server never leaves the loop.

Thanks in advance.
