運營網站，我們經常需要分析用戶的行為、用戶的習慣，用戶看重網站的哪一部分，哪一部分是對用戶有用的之類的信息，這些信息從哪里來，這時我們就需要用到訪問統計系統了。 網上已經有很多的統計系統，如站長統計、百度統計、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現統計的功能呢，而且自己寫的可以實現一些特殊的功能，如登錄，下單行為，能夠更好的融合自己的系統！
下面我們就用ASP.NET MVC 3來實現一個訪問統計系統！首先，使用程序生成一段js代碼，包括讀寫Cookie，及寫入一個唯一值到Cookie中，用來判斷獨立訪客者，再寫入訪問次數及上一個訪問頁面ID值；然后就是獲取客戶端時間，分辨率之類的。
string guid = Guid.NewGuid().ToString();

生成之后再去執行下一個Action，用來寫入一些統計數據，如客戶端IP，瀏覽器信息，訪問頁面來源，當前頁、訪問時間、離開時間等！根據上一個訪問頁面地址、當前地址及上一個訪問頁面ID來判斷是否是刷新操作還是新的訪問頁面，如果是刷新操作則寫入刷新時間，否則寫入上一個頁面的離開時間，由于js的跨域問題，
if (assort.Equals(0))
{
ly = Request.QueryString["Ly"]; //獲取來源URL
currWeb = Request.QueryString["CurrWeb"]; //獲取當前URL
}
else
{
ly = Request.ServerVariables["Http_Referer"];
currWeb = ly;
}

string visitTotal = Request.QueryString["VisitTotal"]; //獲取瀏覽次數

string strAgent = Request.ServerVariables["HTTP_USER_AGENT"];
bool isAlexa = false;
if (strAgent.IndexOf("alexa") >-1) //判斷是否安裝alexa工具欄
isAlexa = true;
string browerName = Request.Browser.Browser; //瀏覽器名稱

if (!string.IsNullOrEmpty(spider))

HttpContext.Application.Lock();
ClickDataAccess clientBasic = new ClickDataAccess();
//刷新操作 需要根據上一個地址和當前地址 來判斷
if (HttpContext.Application["HBCurrWeb_" + SiteID] != null
HttpContext.Application["HBCurrWeb_" + SiteID].ToString().Equals(currWeb)

HttpContext.Application["HBLy_" + SiteID].ToString().Equals(ly)
HttpContext.Application["HBClientId_" + SiteID] != null)
{
clientBasic.UpdateForRefresh(HttpContext.Application["HBClientId_" + SiteID]);

}
else

這里使用Application來存儲對象，當然也可以使用緩存類來做.
暫時沒有解決離開當前網站時的離開時間，當然如果訪問統計系統的域名和被統計的網站域名是同一個頂級域名，則可以做到這點！
訪問統計系統的后臺使用存儲過程來統計分析數據，暫時只寫了一部分功能，僅供大家學習參考！
