Take a look at figure Figure 5.9, “Content-led integration scenario”. As you can see, the CAE and the commerce system stand side by side as equal partners from a users point of view. A user is allowed to request pages from both systems at any given time.
This architecture forces the CAE to synchronize any user sessions on the commerce system with its own. A user that browses the CAE and afterwards visits the WCS must keep his session and vice versa a user browsing the WCS going to the CAE afterwards must keep his state as well.
This section describes how the synchronization of this state is implemented by the CoreMedia CAE.
