TCP Socket Connect through HTTP Proxy

See more Socket/SSL/TLS Examples

Demonstrates how to connect through an HTTP proxy server. Lua

local chilkat = require("chilkat")

-- This example requires the Chilkat API to have been previously unlocked.
-- See Global Unlock Sample for sample code.

local socket = chilkat.Socket.new()

-- 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.http_proxy_hostname = "www.my-http-proxy.com"
socket.http_proxy_port = 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.
local hostname = "192.168.1.108"
local ssl = false
local maxWaitMillisec = 20000
local success = socket:connect(hostname, 5555, ssl, maxWaitMillisec)
if not success then
    print(socket.last_error_text)
    return
end

-- Set maximum timeouts for reading an writing (in millisec)
socket.max_read_idle_ms = 10000
socket.max_send_idle_ms = 10000

-- The ficticious server (in this example) is going to send a "Hello World!"
-- message.  Read it:
local receivedMsg = socket:receive_string()
if not socket.last_method_success then
    print(socket.last_error_text)
    return
end

-- Close the connection with the server
-- Wait a max of 20 seconds (20000 millsec)
success = socket:close(20000)

print(receivedMsg)
