+/**
+ * A connection manager for a single connection. This connection manager maintains only one active
+ * connection. Even though this class is fully thread-safe it ought to be used by one execution
+ * thread only, as only one thread a time can lease the connection at a time.
+ * <p/>
+ * This connection manager will make an effort to reuse the connection for subsequent requests
+ * with the same {@link HttpRoute route}. It will, however, close the existing connection and
+ * open it for the given route, if the route of the persistent connection does not match that
+ * of the connection request. If the connection has been already been allocated
+ * {@link IllegalStateException} is thrown.
+ * <p/>
+ * This connection manager implementation should be used inside an EJB container instead of
+ * {@link PoolingHttpClientConnectionManager}.
+ *
+ * @since 4.3
