Hi,
I really think it is just the opposite. In my opinion the job of the
session is to keep state as easily as possible, it should be one *thing*
likely an extensible data structure that when you choose can be split out
into its parts and do what you like with it. It should not be treated like
organized information because it can change so quickly, it is just data. I
really like the way php handles it, it is one of the only things about PHP
that I do really like.(Yes the temp file stuff is not the greatest, make
sure you have the temp space to match your traffic :)) With Perl we use
Storable and a standard format for the data we put in. We freeze that
structure then insert it into the session table that also has some pieces
of info pulled out of the session for the sake of easy accessibility. For
example the user's email address and yes a timestamp :) The main thing for
me is to be able to add session variables without having to do anything
much and they will be carried through to where they are needed.
Not sure how relevant this is to the topic, but it seemed odd to me to be
talking about how many db fields a session should occupy.. So another way
to put it, if you want to think of a session table, itt should have one
field with unorganized very changeable data, and any other fields should be
things that are not likely to change. We will always need the person's name
and email address in our order system for example, but we might not always
require lot of other fields depending on the situation. The session best
works for me when those transient bits are in the session and not in db
fields. I HATE changing tables, it makes me feel like I screwed up the db
design to begin with..
Thanks,
Eric

I have used session handling for a number projects now. I think I have
always needed just 1 to 3 additional columns.

I don't use SQLite myself, but I keep seeing it used it lots of places.
There is also DBD::CSV, which just might work for this purpose.

Curious. There is also currently my CGI::Session::PureSQL, which is
build to work with PostgreSQL, but not tested on Windows.

I didn't design or code a lot of DFV, but I appreciate your enthusiasm!
I /am/ interested in feedback about the changes I proposed in the DFV 4.0
release on CPAN.
There's lots of new callbacks stuff being used in DFV 4.0. It seems to
be a theme around here...
