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

'  Imagine we've previously saved our encrypted login and password within a JSON config file
'  that contains this:

'  {
'    "http_login": "mCrOmA7mBA7Au9RuJGb9hw==",
'    "http_password": "jJtiI9TgErTTpqBz9JtHBw=="
'  }
