Hello,

Yes, there is. This is by far my "favorite" topic [1] so I wrote a
blog post [2] about it. I would recommend carefulness and a solid
understanding of HTTP and cookies first. It also depends a lot on
whether your backend speaks proper HTTP and won't (mis)lead
Varnish to do TheWrongThing(tm).

Cheers,
