varnish 配置文件分享(sens楊注釋)

前言：
varnish 為目前新興起來的軟件，由于中文文檔比較少，配置文件比較復雜，所以在運用起來也是特別的費勁。一個偶然的機會在一個群里，有位varnish高手（ sens楊）發表了一篇他對varnish配置文件理解的文檔。對于學者來說很有價值。所以轉載了過來。

原文如下：

varnish配置文件原文地址:http://groups.drupal.org/node/63203

注：紅色字體是英文的直接翻譯，有些地方翻譯的不好
綠色部分是一些思考，這個配置對自身的業務配置的很詳細，現在對除了cookie和TTL那部分外其他可以理解80%，慢慢學習體會
