/**

 * /* w  ww . j  av a2  s.co m*/
 * <p>
 * Forwards a request from a servlet to another resource (servlet, JSP file, or HTML file) on the server.<br>
 * This method allows one servlet to do preliminary processing of a request and another resource to generate the response.
 * </p>
 * 
 * <p>
 * For a <code>RequestDispatcher</code> obtained via <code>getRequestDispatcher()</code>, the <code>ServletRequest</code> object has its
 * path elements and parameters adjusted to match the path of the target resource.
 * </p>
 * 
 * <p>
 * <code>forward</code> should be called before the response has been committed to the client (before response body output has been
 * flushed). If the response already has been committed, this method throws an <code>IllegalStateException</code>. Uncommitted output in
 * the response buffer is automatically cleared before the forward.
 * </p>
 * 
 * <p>
 * The request and response parameters must be either the same objects as were passed to the calling servlet's service method or be
 * subclasses of the {@link ServletRequestWrapper} or {@link ServletResponseWrapper} classes that wrap them.
