Python Proxy

>So the program uses the socket module and threading module. it is similar to a technique found here Python Network Programming. Another resource can be found at Tutorial on Threads. I cannot remember where I first read this, these small thread servers seem a little bit excessive but they are actually a great introduction to threads.

import socket as S
import threading

#this is a socket class as a thread.
class Listener(threading.Thread):
	def boot(self,name):
		self.sock = S.socket()
		self.running = 0
		self.partner = S.socket()
		self.name=name
	def run(self):
		self.running = 1
		while(self.running==1):
			data = self.sock.recv(1024)
			if(len(data)>1):
				data2 = data.replace(ProxyPort, callPort)
				data2 = data2.replace(ProxyAddress,callAddress)
				self.partner.sock.send(data2)
				print self.name
				print repr(data)

	def end(self):
		self.sock.close()
		self.running = 0

#setup variables.  This is the address
#your computer uses to connect to. (what you put in your browser).

ProxyAddress = 'localhost'
ProxyPort = '8000'

callAddress = 'www.google.com'
callPort = '80'

myHost = S.socket()
myHost.bind(('localhost',int(ProxyPort)))
myHost.listen(5)

goBetween = Listener()
goBetween.boot('Local Client')
(goBetween.sock,gbAddress) = myHost.accept()

caller = Listener()
caller.boot('Desired Service')
caller.sock.connect((callAddress,int(callPort)))

goBetween.partner = caller
caller.partner = goBetween

goBetween.start()
caller.start()

text = raw_input('functioning to here')

myHost.close()
goBetween.end()
caller.end()

Currently there are a couple issues, if you close out sometimes it locks up. I think sockets have timeouts that I should set.
