See more Amazon Glacier Examples

Demonstrates how to initiate an archive retrieval job to download an archive.

Note: This example requires Chilkat v9.5.0.78 or greater.

    //  See Global Unlock Sample for sample code.

    bool bTls = true;

    bool bAutoReconnect = true;

    //  --------------------------------------------------------------------------
    //  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.
