使 Browser 不缓存页面的过滤器

 

public void doFilter(ServletRequest request, ServletResponse response, FilterChain filterChain) throws IOException, ServletException    {               //清除页面缓存            ((HttpServletResponse) res).setHeader("Cache-Control","No-Cache");              ((HttpServletResponse) res).setHeader("Pragma","No-Cache");                ((HttpServletResponse) res).setDateHeader("Expires", 0);   filterChain.doFilter(request, response);    }
