How to add an item into Shopping cart

[B. Fongo]

I'm working on a shopping cart, and yet to implement Apache::Session.
But before then, I have a question on how to populate a shopping cart
without the page reloading. Is there a way of achieving this using perl?
 
 I believe it is possible to use JavaScript event-handler can be to keep
track of items added into the cart, and later passed to perl to do the
necessary entry into the database.
