(Xojo Plugin) TCP Socket Connect through HTTP ProxyDemonstrates how to connect through an HTTP proxy server.
// This example requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. Dim socket As New Chilkat.Socket // 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.HttpProxyHostname = "www.my-http-proxy.com" socket.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. Dim hostname As String hostname = "192.168.1.108" Dim ssl As Boolean ssl = False Dim maxWaitMillisec As Int32 maxWaitMillisec = 20000 Dim success As Boolean success = socket.Connect(hostname,5555,ssl,maxWaitMillisec) If (success <> True) Then System.DebugLog(socket.LastErrorText) Return End If // Set maximum timeouts for reading an writing (in millisec) socket.MaxReadIdleMs = 10000 socket.MaxSendIdleMs = 10000 // The ficticious server (in this example) is going to send a "Hello World!" // message. Read it: Dim receivedMsg As String receivedMsg = socket.ReceiveString() If (socket.LastMethodSuccess <> True) Then System.DebugLog(socket.LastErrorText) Return End If // Close the connection with the server // Wait a max of 20 seconds (20000 millsec) success = socket.Close(20000) System.DebugLog(receivedMsg) |
