    #tar zxvf ../lighttpd-1.4.23.modcache.v.1.8.0.tar.gz
    #cd lighttpd-1.4.23
    #./configure --with-fam --prefix=/usr/local/lighttpd

    编辑lighttpd配置文件

    server.max-keep-alive-requests = 16
    server.max-keep-alive-idle = 4
    server.max-read-idle = 60
    server.max-write-idle = 360

    #使用epoll作为事件处理
    server.event-handler = "linux-sysepoll"

    #使用sendfile
    server.network-backend = "linux-sendfile"

    #修改最大file descriptions，跟squid相同
    server.max-fds = 65535

    #启用fam作为stat处理方法
    server.stat-cache-engine = "fam"

    #此项打开以后缓存文件时将忽略?，即a.jpg?xxx和a.jpg?xyz都等同于a.jpg
    cache.support-queries = "enable"

    #指定本地缓存存放路径
    cache.bases = ("/srv/lcache")

    #定义刷新
    cache.refresh-pattern = (
            "\.(?i)(flv)$" => "0 fetchall-for-range-request flv-streaming", # to work with mod_flv_streaming for flv files
            "\.(?i)(js|css|xml)$" => "10080", # update js/css/xml every 7 days and on refresh requests
            "\.(?i)(htm|html|shtml)$" => "10080", # update html/htm/shtml every 7 days and on refresh requests
            "\.(?i)(jpg|bmp|jpeg|gif|png)$" => "60", # update graphics files every 2 hours

            "." => "60 update-on-refresh" # default to update every hour and on refresh requests
    )

    #允许purge的ip
    cache.purge-host = "^(192\.168\.)"

    #保存缓存时忽略站点主机名（需要多个站点缓存不同文件的不要启用）
    cache.ignore-hostname = "enable"

    #后端服务器（源站）
    proxy.server               = ( "/" =>
                                   ( "localhost" =>
                                     (
                                       "host" => "192.168.1.15",
                                       "port" => 80

                                 )

    #这项一定要启用
    proxy.worked-with-mod-cache = "enable"

    #设置指定IP允许查看服务器状态和缓存命中率
    $HTTP["remoteip"] =~ "192\.168\.1\.*" {
      status.status-url          = "/server-status"
      status.stastics-url        = "/cache-status"
    }

    #防盗链
    $HTTP["referer"] !~ "^($|http://.*\.(baidu\.com|google\.com|google\.cn))" {
