Hi,

The code is just storing the value of Cart object in the session
provided by asp.net
Now when you store the value in the session you need a key with which
you can identify it uniquely.
Also when you get the value from the session it is of "Object" type
which you have to cast into the object with which you stored that in
the session.

So while storing the value, the code should look like:

Session[KEY_CACHECART] = objCart;

where objCart is object of Cart type. So while retrieving it being cast
back to Cart

This means that the object stored in the session key "Cach:ShoppingCart:" is
explicitly casted to an object of type Cart.

"Cache:ShoppingCart:" is just a name they give the key. It could have been
Cache_ShoppingCart_ or CacheShoppingCart or whatever. But I assume that the
name is a concatenation of strings.

Ok..I see why you are so confused. You don't know what a cache is and how
is it used in asp.net. Take a look at this:
