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

' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.Socket")
set socket = Server.CreateObject("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.
hostname = "192.168.1.108"
ssl = 0
maxWaitMillisec = 20000
success = socket.Connect(hostname,5555,ssl,maxWaitMillisec)
If (success <> 1) Then
    Response.Write "<pre>" & Server.HTMLEncode( socket.LastErrorText) & "</pre>"
    Response.End
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:
receivedMsg = socket.ReceiveString()
If (socket.LastMethodSuccess <> 1) Then
    Response.Write "<pre>" & Server.HTMLEncode( socket.LastErrorText) & "</pre>"
    Response.End
End If

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

Response.Write "<pre>" & Server.HTMLEncode( receivedMsg) & "</pre>"
