Clear the DNS Cache

See more Socket/SSL/TLS Examples

Demonstrates Socket.DnsCacheClear, which clears Chilkat's process-wide in-memory DNS cache so subsequent hostname resolutions perform a new lookup.

Background. The cache is shared by Chilkat objects in the process, so clearing it affects subsequent lookups across the application.
