REST through SOCKS Proxy

See more REST Examples

Demonstrates how to connect through a SOCKS proxy to make REST API calls. VB.NET

Dim success As Boolean = False

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

' This example connects to a REST server through a SOCKS proxy.
' It will connect to the Amazon AWS service for this example.
Dim rest As New Chilkat.Rest
Dim socket As New Chilkat.Socket

' Set the SOCKS proxy domain or IP address, port, and SOCKS version number (4 or 5)
socket.SocksHostname = "192.168.1.100"

' Other properties exist for specifying a SOCKS proxy login and password,
' but these are not used in this example.

' Connect through the HTTP proxy to the Amazon AWS server for the S3 service.

' Use the proxied TLS connection:
success = rest.UseConnection(socket,True)
