I would like to discuss the design of a Large Shopping Mall.

Because of a large shopping  mall can have tens of thousands of items in
it and I plan to keep things fast, I am thinking of doing the following:

1. Split up the products in a tree like directory.
       Shopping -> Foods -> Meats -> Fresh
                                                  -> Smoked

2. Have a directory script that generates the page based on its sub
directories.

2. The leaves directories will be the only directories to contain
products.asc files. In the example, there will be a products.asc in the
Fresh directory and another products.asc in the Smoked directory. ( I
can even name them products_fresh.asc and products_smoked.asc)

3. Make my catalog look in the particular directory which the user
browses, and open the right products file.

4. Somehow manage to share the shopping cart for all these products and
their products.

Has anyone done something similar to this before?

I would like to know is there exists such a "directory script" maybe in
Perl to generate a catalog based on its subdirectories. I think Yahoo,
and other catalogs work like this, right?

Is there a better solution, or would I have a problem sharing the
shopping cart across all the prices and the products in all my
directories?

Will I be better of using a catalog for each leaf subdirectory? I think
I can end up with a huge number of Catalogs, and minivend may not handle
all of them efficiently. Any thoughts on this?
