Is it possible to do donut caching in Varnish?

Question

I'm an ASP.NET developer trying to learn a little bit more about how caching is done on open-source stacks. I was wondering if it's possible to do donut caching on Varnish like how you can with ASP.NET MVC.

I realize that Varnish is a distributed caching system whereas the ASP.NET MVC example is local caching, but is it possible to implement that type of behavior in Varnish?

I'm not familiar with the term "donut caching", but from the description on that page, it sounds similar to Edge Side Includes:
