Take a look at figure Figure 8.1, “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 HCL Commerce must keep his session and vice versa a user browsing the HCL Commerce 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.
