	 * @param isDefaultCharset
	 *            Indicates if the default {@link Charset} for outputting the
	 *            template is being used. While the {@link Charset} may be
	 *            programmatically changed, it is expected in the majority of

	 *            the template. This flag allows static content to be cached in
	 *            bytes (using default {@link Charset}) for improved
	 *            performance.
	 * @param bean
	 *            Bean to potentially obtain data. May be null if
	 *            template contents does not require a bean.
	 * @param connection
	 *            {@link ServerHttpConnection}.
	 * @param templatePath
	 *            Current path for the {@link WebTemplate}. As the path may be
	 *            dynamic (contain path parameters), this is the path to be used
	 *            by links in rending of the {@link WebTemplate}.
	 * @throws HttpException
	 *             If fails to write content.
