' This example requires the Chilkat API to have been previously unlocked.
' See Global Unlock Sample for sample code.
' --------------------------------------------------
' A WebSocket connection begins life as an HTTP GET request containing a few special header fields,
' such as "Upgrade: websocket".
' Your application will use the Chilkat Rest class to send the initial HTTP GET. This allows you
' to use the full capability of the Chilkat Rest class to customize the GET for any particular situation.
' For example:
'
' - If custom HTTP request header fields must be added.
' - If authentication is required, such as OAuth2, OAuth1, Basic HTTP Auth, etc.
' - If HTTPS, SSH Tunneling, Proxies (HTTP or SOCKS), or other advanced connection or TLS features are required.
'
set rest = Server.CreateObject("Chilkat.Rest")
' ------------------------------------------------------------------
' To use TLS, connect to the TLS port (typically 443) and tell the rest.Connect method
' that it's a TLS connection.

' (This adds the required HTTP request headers to the rest object.)
