取代 squid 的 HTTP 加速器 varnish

據說用 3台 varnish 可以抵 12台 squid 來用 , 有時間要來玩一下.



Varnish is a state-of-the-art, high-performance HTTP accelerator. It uses the advanced features in Linux 2.6, FreeBSD 6/7 and Solaris 10 to achieve its high performance.

Some of the features include

  • A modern design
  • VCL – a very flexible configuration language
  • Load balancing with health checking of backends
  • Partial support for ESI
  • URL rewriting
  • Graceful handling of "dead" backends
  • more features

Varnish is free software and is licenced under a modified BSD licence. Please read the introduction to get started with Varnish.
