session is not belongs to the web browser...when the first time a
request come from a user to a server the sever automitacally give hime
a session.. what ever the browser the user is use.
u can check this by copyeing the url and paste it in another browser
after a successfulyy login-- u see that all the autheticate page you
are browsing
cockies is used by some of the web hoster to track u .to find that u r
browsing their site for the first time or for the seccond time . when
basically we check on save pass check box this is save in our hard disk
as cockie. so seccond time when we logon to that particuler site that
cockie is send user name and password for us.u can check this by opening cockie folder what is under document and
settings E:\Documents and Settings\UR_USER_NAME\Cookies folder and if u
delete a cockie what may e set for yahoo or hotmail so nexttime when u
going to logon their pages the auto loging system will not work
HTTP protocols are stateless, so one state dont know about other state.
session id is nedded to be handeld by server side scipting .usually it
is handeld by programer. so it is basically our responsibility to play
with a session, check it in every pages.. send it to one page to other
u can do that in many when like by checking when u give him the id
their is many way u can handel a id, like for a page-the id will valid
only in a page in a whole session or for some default timing.
if in ur websites theire is no securitu like no user name and login
system then u can easily forget aout this session and cockie things
bye
take care
