運(yùn)營網(wǎng)站，我們經(jīng)常需要分析用戶的行為、用戶的習(xí)慣，用戶看重網(wǎng)站的哪一部分，哪一部分是對(duì)用戶有用的之類的信息，這些信息從哪里來，這時(shí)我們就需要用到訪問統(tǒng)計(jì)系統(tǒng)了。 網(wǎng)上已經(jīng)有很多的統(tǒng)計(jì)系統(tǒng)，如站長統(tǒng)計(jì)、百度統(tǒng)計(jì)、谷歌分析之類的，別人的東西始終是別人的，為什么我們不自己實(shí)現(xiàn)統(tǒng)計(jì)的功能呢，而且自己寫的可以實(shí)現(xiàn)一些特殊的功能，如登錄，下單行為，能夠更好的融合自己的系統(tǒng)！
下面我們就用ASP.NET MVC 3來實(shí)現(xiàn)一個(gè)訪問統(tǒng)計(jì)系統(tǒng)！首先，使用程序生成一段js代碼，包括讀寫Cookie，及寫入一個(gè)唯一值到Cookie中，用來判斷獨(dú)立訪客者，再寫入訪問次數(shù)及上一個(gè)訪問頁面ID值；然后就是獲取客戶端時(shí)間，分辨率之類的。
