/**
* An example showing how to setup an HttpClient that uses the
* Default SSLContext
* to make an example request against a secure host on the public internet.
*
* For most people, this will be using the default Protocols, CipherSuites and Certificate bundles that come with the
* system and/or JDK. This should be doing the 'right thing' in most cases, but of course, this depends on the specifics
* of how the system and/or JDK has been installed or configured.
*
* IMPORTANT:
* We are not security experts and you should do your own research or consult an expert when configuring your own
* secure HttpClients for Production use.
