Usage

From source file:org.wings.session.PortletWingServlet.java

/**
 * create a Device that is used to deliver the content, that is
 * not session specific, i.e. that is delivered by the SystemExternalizer.
 * The default// ww  w.  j a v  a2  s .  c  o m
 * implementation just creates a ServletDevice. You can override this
 * method to decide yourself what happens to the output. You might, for
 * instance, write some device, that logs the output for debugging
 * purposes, or one that creates a gziped output stream to transfer
 * data more efficiently. You get the request and response as well as
 * the ExternalizedResource to decide, what kind of device you want to create.
 * You can rely on the fact, that extInfo is not null.
 * Further, you can rely on the fact, that noting has been written yet
 * to the output, so that you can set you own set of Headers.
 *
 * @param request  the HttpServletRequest that is answered
 * @param response the HttpServletResponse.
 * @param extInfo  the externalized info of the resource about to be
 *                 delivered.
 */

        ExternalizedResource extInfo) throws IOException {
