' 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 an HTTP proxy.
' It will connect to the Amazon AWS service for this example.
' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.Rest")
set rest = CreateObject("Chilkat.Rest")
' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.Socket")
set socket = CreateObject("Chilkat.Socket")

' Set the HTTP proxy domain or IP address, and port.
socket.HttpProxyHostname = "192.168.1.100"
socket.HttpProxyPort = 8088

' We want to tell the socket object that we're doing HTTP over the proxy connection.
' This is because an HTTP proxy used for other protocols (IMAP, SMTP, SSH, FTP, etc.) 
' can require some internal differences in behavior (i.e. how we do things).
socket.HttpProxyForHttp = 1

' Other properties exist for specifying a proxy login, password, and authentication method (such as NTLM),
' 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,1)
