有關cookie中遇到的 utma utmz 的解釋

由于第一次研究cookie，在分析校内的cookie的時候，遇到了一些__utma utmz的Name，參數的内容完全分析不懂，經多方求教，終于知道了原來那些代碼竟然是Google的免費網站統計系統産生的資訊（垃圾代碼害得我浪費了整整一天），Down下來了它的生成檔案：Urchin.js 幾千行代碼看的我腦袋發木，最後百度搜尋尋求不到結果，求助于Google，才得到了如下的資訊：

This article/section is a stub.

It is here because it was planned, created to drop some preliminary notes. Statements may be wrong,and the style and structure may suck. Feel free to add further notes orsuggestions, rewrite sections or the whole into somethingunderstandable.

The cookies named:

• __utmv is used for user-custom variables in Analytics

__utma
__utmz
      

...and others are part of Google Analytics, specifically the Urchin tracking module. These cookies track usage on sites that use Google Analytics.

Some details:

• __utmz tracks where a visitor came from (search engine, search keyword, link)

• __utma tracks each user's amount of visits, first, last visit.

• __utmb and __utmc are used totrack when a visit starts and ends to some decent time resolution (cexpires quickly). If you look at cookie state changes (e.g. using firecookie), you will see these change a lot .

如上，英文的内容實在讓人看得頭痛，下面簡要翻譯下各個參數的内容：

__utmz：跟蹤通路者是從哪裡來的(搜尋引擎,搜尋關鍵字,連結位址);

__utma：跟蹤每個使用者的大量通路,第一次,最後一次;

__utmb和__utmc是跟蹤每個使用者的通路時間，從開始到結束。

好了，現在了解了這些無關緊要的資料了，算法還未分析完畢，先把代碼貼上，希望牛人如果看到的話給一下具體算法，到底如何計算出這幾個參數的~
