If you are using Oracle ATG Web Commerce’s multisite feature, you may want to provide users with the ability to place items from multiple sites in a single order. You do not need to do any additional configuration to use this feature; the ShoppingCart is registered as a shareable component by default and works the same way in a multisite environment as in a single site.

To register the ShoppingCart as a shareable component, it is added by default to the NucleusComponentShareableType component:

shareableTypes+=/atg/multisite/ShoppingCartShareableType

The shareable component that refers to the ShoppingCart can be configured in the following properties file:

/atg/commerce/ShoppingCartShareableType.properties

See the ATG Multisite Administration Guide for information on shareable components and how to use sharing groups in your multisite configuration.
