How To Implement No Caching On Jsf Pages

Currently in that place are two ways I know that tin produce this.

1.) By implementing Filter in addition to manually overriding the cache controls. See code below (note: non my master copy I institute this somewhere else long fourth dimension ago):

 @WebFilter(servletNames = { "Faces Servlet" }) world flat NoCacheFilter implements Filter {   @Override  world void doFilter(ServletRequest req, ServletResponse res,    FilterChain chain) throws IOException, ServletException {   HttpServletRequest asking = (HttpServletRequest) req;   HttpServletResponse answer = (HttpServletResponse) res;    if (!request.getRequestURI().startsWith(     request.getContextPath() + ResourceHandler.RESOURCE_IDENTIFIER)) {    // Skip JSF resources (CSS/JS/Images/etc)    response.setHeader("Cache-Control",      "no-cache, no-store, must-revalidate"); // HTTP 1.1.    response.setHeader("Pragma", "no-cache"); // HTTP 1.0.    response.setDateHeader("Expires", 0); // Proxies.   }    chain.doFilter(req, res);  }   @Override  world void init(FilterConfig filterConfig) throws ServletException {   }   @Override  world void destroy() {   }  } 

2.) The i I preferred, using omnifaces' CacheControlFilter. More data available at: http://showcase.omnifaces.org/filters/CacheControlFilter. To role but involve to add together the filter in addition to integrate alongside facesServlet.

 <filter>  <filter-name>noCache</filter-name>  <filter-class>org.omnifaces.filter.CacheControlFilter</filter-class> </filter>  <filter-mapping>  <filter-name>noCache</filter-name>  <servlet-name>Faces Servlet</servlet-name> </filter-mapping>
