服务器网页缓存的深入分析

三、lighttpd

lighttpd默认是没有开启expire模块的，需要我们在使用是手工开启这个模块支持。把mod_expire前面的“#”号去掉。

# vi  /usr/local/lighttpd/etc/lighttpd.conf
                                "mod_expire",

设定过期时间

    * 设定指定url的过期时间：

expire.url = (
       "/images/" => "access 3 hours",
       "/admin/" => "access 3 hours",
       "/area/" => "access 3 hours",
       "/calendar/" => "access 3 hours",
       "/common/" => "access 3 hours",
       "/front/" => "access 3 hours",
       "/inc/" => "access 3 hours",
       "/jeditor/" => "access 3 hours",
       "/js/" => "access 3 hours",
       "/script/" => "access 3 hours",
       "/theme/" => "access 3 hours",
       "/upload/" => "access 3 hours",
       "/view/" => "access 3 hours",
       "/help/" => "access 3 hours",
       "/htm/" => "access 5 minutes"
       )

设置Etag

在配置文件中增加，etag.use-inode="disable"（i节点不参与etag的运算），保证多台服务器生成的Etag值一致。
