Be aware that glibc sometimes puts some heap allocations in
shared library space rather than heap space using mmap,
especially if you have large ones (as a 400M starting heap
would seem to indicate). See if you can determine if this
is happening; top will show the library allocations as LIB.
Have you considered using the ss command line argument
(varies from JVM to JVM; java -X usually tells you what to
do; sometimes it's -Xoss and/or -Xss; usually parameters
like 64k are sufficient but sometimes you may need to go
higher . . .

You can't really avoid refresh.
Consider that people can double-click on a submit button or

Other than the timing, there is very little to distinguish this

You forgot: never use servlet instance variables.
This alone is the most common servlet programming bug I've
ever seen, and I see it again and again and again.
I think the containers should use reflection to sniff

refuse to load the
Best to do this by layering your own abstraction on top of Sessions.
That's what we do [although we don't use it to solve this particular

No, it says indentation of 4, and it also says that tabs are
equivalent to 8 spaces. This is precise and sufficient and
will work with any virtually any editor [assuming people know
how to use their editor]. Hint: if your editor displays
a single hard-tab (^I in the file) as four spaces

What's a client? For instance, if it's truly an attack, it would be
trivial to spoof IP addresses. And with entire corporations behind
NAT firewalls, simply setting the number of sessions per IP addresses
to a `small' number would not work.
Or, are you saying, don't initiate a session until

Exactly. It would have been nice if JSP was done right from the start
instead of having an original goal of attempting to provide a solution to
strictly compete with ASP.
My thought is that JSP was `done right from the start' (at least, with
custom taglibs)---it just doesn't solve the whole
This is probably due to the new SecureRandom-based session IDs.
There is an option to turn that off somewhere.
