/**
 * 

* EasySSLProtocolSocketFactory can be used to creats SSL {@link Socket}s * that accept self-signed certificates. *

*

* This socket factory SHOULD NOT be used for productive systems * due to security reasons, unless it is a concious decision and * you are perfectly aware of security implications of accepting * self-signed certificates *

* *

* Example of using custom protocol socket factory for a specific host: *

 *     Protocol easyhttps = new Protocol("https", new EasySSLProtocolSocketFactory(), 443);
 *
 *     HttpClient client = new HttpClient();
 *     client.getHostConfiguration().setHost("localhost", 443, easyhttps);
 *     // use relative url only
 *     GetMethod httpget = new GetMethod("/");
 *     client.executeMethod(httpget);
 *     
*

*

* Example of using custom protocol socket factory per default instead of the standard one: *

 *     Protocol easyhttps = new Protocol("https", new EasySSLProtocolSocketFactory(), 443);
 *     Protocol.registerProtocol("https", easyhttps);
 *
 *     HttpClient client = new HttpClient();
 *     GetMethod httpget = new GetMethod("https://localhost/");
 *     client.executeMethod(httpget);
 *

* DISCLAIMER: HttpClient developers DO NOT actively support this component. * The component is provided as a reference material, which may be inappropriate * for use without additional customization. *
