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

* Download the contents of a PDF file into the bd object.

IF (lnSuccess = 0) THEN
    * This will happen if the response status code was 400 or greater,
    * or if the request could not be sent, or if no response was received.
    * 
    * In other words, success will only be 1 if bd contains the desired content at the URL (not an error response).

        * Examine the response body.
