public class HttpURLConnection
extends HttpURLConnection

Provides a HttpURLConnection wrapper around HttpClient's HttpMethod. This allows existing code to easily switch to HttpClieht without breaking existing interfaces using the JDK HttpURLConnection. Note 1: The current implementations wraps only a connected HttpMethod, ie a method that has alreayd been used to connect to an HTTP server. Note 2: It is a best try effort as different version of the JDK have different behaviours for HttpURLConnection (And I'm not even including the numerous HttpURLConnection bugs!).
