See chapter six of the ESI spec: http://www.w3.org/TR/esi-lang

When an ESI template is processed, a separate request will need to be made for each include encountered. Implementations may use the original request's headers (e.g., Cookie, User-Agent, etc.) when doing so. Additionally, response headers from fragments (e.g., Set-Cookie, Server, Cache-Control, Last-Modified) may be ignored, and should not influence the assembled page.

Given the above, and given your explanation of your app disgarding cookies, then I'm going to go out on a limb and say i`not possible`.
