What is better to use?

Question

Hi all,
1) request.getSession(true) or request.getSession(false), I know the different and yet what is the best to use?
2) In every jsp page of my application I use session = request.getSession(false/true). (Depends on the first answer), are this ok? Or I shell not use it and only use session. (I did (false) becuase I wanted to know if session is dead).
Thanks all in advance,
Sasi

Hi all,
1) request.getSession(true) or
request.getSession(false), I know the different and
yet what is the best to use?The best one to use is the one that does the one you want. Do you want to create a new session? Then use (true). Want to get null if there is no session? Then use (false).
2) In every jsp page of my application I use session
= request.getSession(false/true). (Depends on the
first answer), are this ok? Or I shell not use it and
only use session. (I did (false) becuase I wanted to
know if session is dead).There is actually a few ways to check if the session died. One is to use getSession(true) so you always get a session, then test session.isNew(). This will have the same effect as calling getSession(false), and checking if session == null (and if it is, at some point creating a new session).
If you always want a new session made, then you should probably use getSession(true) with the isNew() check. If there are cases you want to prevent session creation, or delay it for a while then you should use getSession(false).
