(Perl) Asynchronous SSL Client (Deprecated) Example

Notice: The functionality described here is deprecated and replaced by a newer model for asynchronous method calls. The newer model was introduced in Chilkat v9.5.0.52, and is identified by methods having names ending in “Async” which return a task object.

Demonstrates how to connect to an SSL server, send a simple message, receive a simple response, and disconnect. This example uses the asynchronous methods to connect, send, and receive.
