So there is a new shiny blogging platform out called Ghost. Looks pretty good to me.
If you want to run it behind Varnish, you’ll soon notice it has the usual problem of setting session cookies everywhere leading to 0% hit rate.
I have written a Varnish VCL configuration for filtering this in the necessary places, while keeping the admin interface working still.
You can find it here:

Have fun.
