The Nginx cache is a "look we can do caching as well" whereas Varnish is only built for caching.

The simple stuff should be reasonably comparable. -- Phone: +47 21 98 92 61 / Mobile: +47 958 39 117 / Skype: per.buer *Varnish makes websites fly!* Whitepapers <http://www.varnish-software.com/whitepapers> | Video<http://www.youtube.com/watch?v=x7t2Sp174eI> | Twitter <https://twitter.com/varnishsoftware>
