/**
 * A Connection provides a convenient interface to fetch content from the web, and parse them into Documents.
 * 

* To get a new Connection, use {@link org.jsoup.Jsoup#connect(String)}. Connections contain {@link Connection.Request} * and {@link Connection.Response} objects. The request objects are reusable as prototype requests. *

*

* Request configuration can be made using either the shortcut methods in Connection (e.g. {@link #userAgent(String)}), * or by methods in the Connection.Request object directly. All request configuration must be made before the request is * executed. *
