i've been doing some research around websites like www.dabs.com etc.
into how their shopping carts work. and it seems that most sites use
ASP.
i don't want to use asp.

So why are so many companies using ASP for their shopping carts, and
how if possible could i use php (and javascript?) to create my own
shopping basket.

if possible links to tutorials?

Thank you
