//  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.

//  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)

//  message.  Read it:

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