 /**

  *    - disabled_wire: This is a performance improvement that will disable
  *         some debugging functionality with cURL.  The functionality
  *         it disabled allows you to see the exact HTTP request sent over
  *         the wire.
  *    - progress: Set to true to enable progress function callbacks. Most
  *         People don't need this, so it has been disabled by default.
