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

Dim rest As New Chilkat.Rest

// Connect to the Amazon AWS REST server in the desired region.
Dim bTls As Boolean
bTls = True
Dim port As Int32
port = 443

bAutoReconnect = True
Dim success As Boolean
success = rest.Connect("glacier.us-west-2.amazonaws.com",port,bTls,bAutoReconnect)

// --------------------------------------------------------------------------
// Note: The above REST connection and setup of the AWS credentials
// can be done once.  After connecting, any number of REST calls can be made.
// The "auto reconnect" property passed to rest.Connect indicates that if
// the connection is lost, a REST method call will automatically reconnect
// if needed.
