JSF page refresh

To refresh a JSF page the following piece of code is useful

FacesContext context = FacesContext.getCurrentInstance();
String viewId = context.getViewRoot().getViewId();
ViewHandler handler = context.getApplication().getViewHandler();
UIViewRoot root = handler.createView(context, viewId);
root.setViewId(viewId);
context.setViewRoot(root);


If your page is not getting refreshed due to browser caching

 FacesContext facesContext = event.getFacesContext();
HttpServletResponse response = (HttpServletResponse) facesContext.getExternalContext().getResponse();
response.addHeader("Pragma", "no-cache");
response.addHeader("Cache-Control", "no-cache");
response.setHeader("Cache-Control", "no-store");
response.addHeader("Cache-Control", "must-revalidate");
