 com.jcorporate.expresso.core.servlet.CheckLogin
| CheckLogin | | final public class CheckLogin (Code) | | CheckLogin accepts an HttpServletRequest and HttpServletResponse object
pair, and attempts to check if the user is logged in.
If not, CheckLogin tries to log the user in via a cookie from the
client. If this is not possible, the user is logged in as "NONE".
It has now been modified to be a Singleton Object rather than having a new
object allocated with each request.
Example Usage:
CheckLogin.getInstance().checkLogin(request,response);
