Hi,
I am doing any fundamental mistake??
please anybody help or can u please tell me how to handle this situation
when user hits any JSP needs to check wether he logged in or not.
if he is not login needs to redirect to Login URL.
read the previous posts but i am not clear
please anybody help me
Thanks,
