# To connect through an HTTP proxy, set the HttpProxyHostname
# and HttpProxyPort properties to the hostname (or IP address)
# and port of the HTTP proxy.  Typical port numbers used by
# HTTP proxy servers are 3128 and 8080.
socket.put_HttpProxyHostname("www.my-http-proxy.com")
socket.put_HttpProxyPort(3128)

# Important:  Your HTTP proxy server must allow non-HTTP
# traffic to pass.  Otherwise this does not work.

# Connect (via the HTTP proxy) to port 5555 of 192.168.1.108.
# hostname may be a domain name or IP address.

# Set maximum timeouts for reading an writing (in millisec)

    print socket.lastErrorText() + "\n";

# Close the connection with the server
# Wait a max of 20 seconds (20000 millsec)
