[Python] how to receive a socket message with an empty data?

i have a socket client and a socket server.

(the server is in python, and is synchroneous.)

sometimes the clients send an empty string. i'm required to identify this situation, and return a response.

with this code, the server just keeps on waiting, and the client's don't get anything in return, unless it sends something mroe "fat"

how can i capture the empty message? is it at all possible?

that's my server code:

import SocketServer

def multi_threaded_socket_server():

class MyRequestHandler(SocketServer.BaseRequestHandler):
def handle(self):
while True:
print 'waiting for client calls...'
received = self.request.recv( PACKET_SIZE )
(handle request... )
