#  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.
hostname = "192.168.1.108"
ssl = false
maxWaitMillisec = 20000
success = socket.Connect(hostname,5555,ssl,maxWaitMillisec)
if (success != true)
    print socket.lastErrorText() + "\n"
    exit
end

#  Set maximum timeouts for reading an writing (in millisec)
socket.put_MaxReadIdleMs(10000)
socket.put_MaxSendIdleMs(10000)

#  The ficticious server (in this example) is going to send a "Hello World!"
#  message.  Read it:

receivedMsg = socket.receiveString()
if (receivedMsg == nil )
    print socket.lastErrorText() + "\n"
    exit
end

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

print receivedMsg + "\n"
