JSF Storing data into a cookie

Question

I want to store some user data into a cookie so it's always there when they load the web app, even if the session has expired.

What's the best way of doing this with JSF?

Answer 1

Writing to a cookie:

FacesContext.getCurrentInstance()
 .getExternalContext()
 .addResponseCookie("CookieName", "value", null);

Reading the cookie

Map<String, Object> requestCookieMap = FacesContext.getCurrentInstance()
   .getExternalContext()
   .getRequestCookieMap();
