Subject RE: how to keep session alive on the server side
Date Tue, 23 Nov 2010 21:15:22 GMT
I am little reluctant to use HttpSession.setMaxInactiveInterval() for couple of reasons:

1) I don't know ahead of time how long these operations will take. SO I don't have a good
value to set the MaxInactiveInterval to.
2) I need to design for my clients crashing or losing connectivity with me. So I can't use
a negative value either (i.e. never expires).
