Cache Reverse Proxy - Varnish

 
Written by Wayne Ye  Friday, January 11, 2013

Introduction

Varnish is an HTTP accelerator, the official page is: https://www.varnish-cache.org/.

Varnish stands in front of the web application server to be a cache reverse proxy (also can be a load balancer), it can simply cache all the static resources in memory, and can also be powerfully configed using VCL (Varnish Configuration Language, a DSL for Varnish configuration) to cache dynamic content, in addition, Varnish implements ESI (Edge Side Include) standards to provide ability to cache static parts of the page.

Introduction

On the homepage of nxing wiki, there used to be one sentence which really impressed my very much when I first time to take a look at it and learn it three years ago:

Apache is like Microsoft Word, it has a million options but you only need six. Nginx does those six things, and it does five of them 50 times faster than Apache.  --Chris Lea
