Example: Http.ResumeDownload method

Demonstrates the ResumeDownload method. C#

bool success = false;

//  To demonstrate resuming a download, we've created a file on the chilkatsoft.com
//  web server that contains the first 82,379 bytes of the full  279,658 bytes of the hamlet.xml file.

//  We'll first download the partial file, and pretend it was a previous incomplete attempt to download the entire file.
