Would it be possible to store the values in a
singleton Hashmap whose key is the session id and
value is the object containing user entered data?
..Instead of using session vars.
What would be the pros/cons/considerations?
I guess when the session expires you need to expire
the object. Would it be a huge use of resources?
Might it be considered for secure data with users not
accepting cookies? or is it time for SSL at this
point?
Just trying to learn.
