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

loHttp = CreateObject('Chilkat.Http')

* Implements the following CURL command:

* curl -i -X POST \
*   -u 2498righ8wr6aihe98rt8rhowirtyw9er6twe80rtywrehrt:nerf254578uh8rgt7y3h57358ouyth387h8h53h6yyh80hh578per9y7u5ruyuy4 \
