Hi,
I think that this is a very simple questin but can somebody tell me why
sessions are better than cookies (or vice versa!). I could off-hand think of
the following reasons why i would prefer to user sessions rather than
cookies :
1 - Cookies may hv been turnedoff on the client.
2 - Instead of writng code to read/write cookies in JS and/or servlets, the
session-validation etc can be done only once on the server-side with queries
to the database(if need be).
3 - No need of assuming the expiry date of the cookie. Servlet can simply
invalidate the session.
The necessity of cookies I feel would be when we need to store
informtion for longer than the current session. However, I am toying with
the idea of writing the session attributes to a file and then reading it
from there. But I do not know how i can differentiate different
session-attributes to different machines. Can somebody throw some light on
how I can implement server-side cookies(!!).
thanks.
raaj.
