Hello All,
A simple one? I have my session defined in a servlet thus:
HttpSession session = req.getSession();
session.setAttribute(userSession, h); // (h = HashMap)
how or where do define session parameters such as expiry? I would
ideally like my session to die when I call a

In particular, session expiration can be set in web.xml.
sessions can also be expired programmatically via its invalidate() method.

The question is: Why turn a hashmap into an array just to take its
length when you already have a method that returns the number of
sessions? This will make the life of people who write session managers
that DON'T store all the active sessions in memory easier.

Another thing to consider when evaluating object pooling is the expected
lifetime of the objects. On modern JVMs with generational memory stores,
objects with a short lifespan (say the duration of a single HTTP request)
will probably never leave the nursery. Pooling these kinds of objects
The optimal solution would be the ability to enable/disable each type of
object pooling with a config parameter so that tomcat admins can tune Tomcat
to perform best for their OS/JVM.
Like you can currently do with Jasper and JSP tag pooling.

The performance hit of obtaining/recycling an object can be greater than

I agree that the MimeHeaders example is not really an example of an object

GC at all costs was the wrong approach. Keep in mind, the utils stuff that
