Hmmm, interesting. I have a client who wants me to stack carts on a
page so her commercial clients can do all their shopping in one trip.
The ASP equivalent she wants me to clone in PHP is the business gift
style at
http://www.godiva.com . You can get several items for one
client, then start another cart before checking out, later sending
batches of gifts to several people with different messages for each
batch. I wonder if they're doing something like you mention here,
but with different session names. (They have changed their setup and
cart flow since she and I first discussed it, and, checking again
tonight, I see that it is changed yet again.) The problem I see with
it is getting the cart page to grab all session data and blend it on
that and subsequent pages for checkout. Sessions are usually meant for
a single entity and follow through semi-linearly.
Yes, I know this is a sidestep from the OP's question but it appears
that handling might work in the same fashion.
(Remember this one, Rajesh?)

Has anyone else noticed that not a single one of their book links
works on the Linux Central site? After entering some titles into
the LC search box and coming up empty, LC obviously doesn't carry
_any_ of the books they refer to. Very strange. I wonder whose DB
they're tracking. <vbg> They don't ACK mail on it, either.
Hmm, he calls this a handler and uses it for multiple

Why use a database for session data, or are you merely catching
that as well as the "good stuff" such as order data?

Good idea. I (too) often forget how useful Google, et al, can be.
