+/**
+ * A client-side request director.
+ * The director decides which steps are necessary to execute a request.
+ * It establishes connections and optionally processes redirects and
+ * authentication challenges. The director may therefore generate and
+ * send a sequence of requests in order to execute one initial request.
+ *
+ * <br/><b>Note:</b>
+ * It is most likely that implementations of this interface will
+ * allocate connections, and return responses that depend on those
+ * connections for reading the response entity. Such connections
+ * MUST be released, but that is out of the scope of a request director.
