Thanks Igor,
I know the reasons for the locking. I just want to
pinpoint some use cases. I will test your solution for images, but it will take
some time, currently I am on the opposite end of our application, at business
and data layer.

well,
in order to not let the internal state be corrupted requests have to be
processed in sequence they originated from the user. a good and easy way to do
this is to lock on session making sure that requests from that user are
basically serialized. we really havent found a better way to do this. it has
plenty of drawbacks but until we come up with a good clean solution i dont
think we are going to change that.
as far as the images, as ive said
there are ways to serve them in a nonblocking fashion by using a dynamic
resource or a custom target. the target is the place that chooses the lock -
or sometimes no lock at all. you can build all kinds of nonblocking behaviors
if you want by creating your own request targets.

Hi,
I see your points. In
my opinion, *any* database query (but not only
database) can be long
operation. At that time your code is sitting in idle
loop waiting for
database (located on another PC). In that time the CPU can
do other
useful job for the same client (session). I pointed out another use
case
with images from database, see my other response. If the session is
not
locked, the image will appear in parallel (quicker), while with
locked
session, they will appear one by one (slower, because of lost
time waiting
for database).
