Socket programming in python is very user friendly user. user focusing on the application layer more than the network layer in python.

Creating an incoming socket :

*create a socket serverSocket in the __init__ method of the Server Class.

def __init__(self, config): 
    # Shutdown on Ctrl+C

    signal.signal(signal.SIGINT, self.shutdown) 

    # Create a TCP socket

    self.serverSocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

    # Re-use the socket

    self.serverSocket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)

    # bind the socket to a public host, and a port   

    self.serverSocket.bind((config['HOST_NAME'], config['BIND_PORT']))


    self.serverSocket.listen(10) # become a server socket

    self.__clients = {}

Accept client and process:

while True:

    # Establish the connection 
    (clientSocket, client_address) = self.serverSocket.accept() 

    d = threading.Thread(name=self._getClientName(client_address), 

    target = self.proxy_thread, args=(clientSocket, client_address))

    d.setDaemon(True)

    d.start()

Redirecting the traffic:

# get the request from browser 
request = conn.recv(config['MAX_REQUEST_LEN']) 

# parse the first line

first_line = request.split('\n')[0]

# get url

url = first_line.split(' ')[1]
