HOST = '127.0.0.1'                 # Symbolic name meaning the local host
PORT = 50007              # Arbitrary non-privileged port

while 1:
    conn, addr = s.accept()
    print 'Connected by', addr
    data = conn.recv(1024)
    if not data: break
    file = open(data[4:data[4:].find(' ')+4]) # extracts filename from request
    str1 = file.read()
    file.close()
    data = str +str1
    conn.send(data)
    conn.close()
