Cookies are used for dynamic HTML snippets, which are snippets that cannot be cached because they contain user specific content. Fragments that the CAE delivers to the commerce server should never include such dynamic HTML snippets because this would prevent a CDN or other caching infrastructure from caching complete WCS pages.
But if the CAE does only return static HTML within the fragment responses to the commerce system, it does not need any cookies. Everything that needs cookies in a fragment must instead be implemented by using dynamic fragments, explained in Section 8.2.1, “Using Dynamic Fragments in HTML Responses”.
For solving the same origin policy problem that would occur for dynamic (Ajax) requests against the CAE, that originated in a static CAE fragment delivered via the WCS, CoreMedia provides a solution described in Section 5.1.2, “Solutions for Same-Origin Policy Problem”
