Nginx: PV、UV、独立IP
做网站的都知道，平常经常要查询下网站PV、UV等网站的访问数据，当然如果网站做了CDN的话，nginx本地的日志就没什么意义了，下面就对nginx网站的日志访问数据做下统计；
概念：
- UV(Unique Visitor)：独立访客，将每个独立上网电脑（以cookie为依据）视为一位访客，一天之内（00:00-24:00），访问您网站的访客数量。一天之内相同cookie的访问只被计算1次
- PV（Page View）：访问量,即页面浏览量或者点击量,用户每次对网站的访问均被记录1次。用户对同一页面的多次访问，访问量值累计
- 统计独立IP：00:00-24:00内相同IP地址只被计算一次,做网站优化的朋友最关心这个
先声明下环境，此次运行的nginx版本1.7，后端Tomcat运行的是动态交互程序（需进行用户认证，如果是静态页面则抓不到cache值，$http_cookie是空值），就是这样；

注：$http_cookie这个里面的值是一个一个cookie的值，中间以“;”分隔
