Python socket module. Connecting to an HTTP proxy then performing a GET request on an external resource

Question

To begin with, I understand there are other modules such as Requests that would be better suited and simpler to use, but I want to use the socket module to better understand

Answer 1

Python 3 requires the request to be encoded. Thus, expanding on David's original code, combined with Steffens answer, here is the solution written for Python 3:

def connectThroughProxy():
    headers = """GET http://www.example.org HTTP/1.1
                Host: www.example.org\r\n\r\n"""

    host = "192.97.215.348" #proxy server IP
    port = 8080              #proxy server port

    try:
        s = socket.socket()
        s.connect((host,port))
        s.send(headers.encode('utf-8'))
        response = s.recv(3000)
        print (response)
        s.close()
    except socket.error as m:
       print (str(m))
       s.close()
       sys.exit(1) 

This allows me to connect to the example.org host through my corporate proxy (at least for non SSL/TLS connections).
