caching anon users', & auth users' ESI, content specifically in Laravel PHP framework apps?

[grantksupport at operamail.com]

I'm trying to get varnish to cooperate with (a new-installed) laravel php framework's sesion caching (http://laravel.io/forum/12-16-2014-laravel-redis-session-storage-varnish-reverse-proxy-cache-how-to-preventstrip-cookies-to-enable-varnish-caching)

Currently, when using redis for session storage, laravel sets a COOKIE -- for both authenticated & anonymous users

	Cookie: laravel_session=eyJ...UifQ%3D%3D 

For anon users, and for ESI blocks with auth'd users, Varnish should cache.

What's the correct method for ensuring Varnish caches in these cases, when using a Laravel app?

Can/should it be handled only in Varnish VCL -- stripping the cookie?  If so, how's the ID of auth vs anon cookie best handled?

or, must in be done in concert with, or solely within, the Laravel app?
