You have to update something on the server-side to maintain status of the
CART. Without frames it is easy to do by just passing the data back and
forth via the cgi in hidden fields. I don't see how to do this with frames
(nor am I that interested).
So they must write the data to a database and then later they must delete
the records created. What I don't like about that is that you could
consume more space than is allotted. Also, better be sure you delete the
right records..

Umm. I really like using the rdbms for just what you mentioned. I have a
sql form where I can just give the name of the database and I just insert
the sql queries to get the results back. Very nice for just looking up
info from data.
I have to do this shopping cart for someone who uses one of those hosts
who don't offer any rdbms. A side note, I had to do a job for a web
developer who had their site with valueweb. Can you imagine doing the work
without access to telnet? I had to write cgi's to communicate with the
database server. Ughhh.. I tried to import a file via a cgi I wrote for
importing files into msql and it ran out of memory. The file was about 11
meg or so. I thought I could do just one line at a time and not consume
any memory (I thought I was deleting any memory from one insert to the
next but perhaps not). I ended up just doing a
msql Database < file_to_insert
and it took awhile but worked.
But to get back on track. These people are using hosting companies that
are state-of-the-art for 1992. It is flat-file (like I was just a year
ago).

I think I would allow resizing or do it for 640x480. I looked at the site
at 800x600.
I am a big fan of benchmarking. Thanks for the tip and feedback.
