【编程】开源(OpenSource) - 反向链接(Referrers)系统
网络整理 - 08-10
反向链接(Referrers)系统可以很好的显示反向链接，目前很多站点上显示的最新来源（referer）统计都是用的是Stephen的referrer统计系统，比如 Booso 反向链接(Referrers)统计系统，还有一个朱传伟的反向链接统计服务不知道是不是他自己实现的。总之，网上提供这些反向链接(Referrers)系统不是服务不好，就是定制性不好，所以，干脆，我烦了，自己花一天时间写了一个，并且公开源代码，基本上架构和功能都用了，但是还需要完善。
由于我没有支持 ASP + Access 的主机，所以无法为大家提供服务，希望有哪个同仁可以提供这个服务？或者 CSDN 会提供这个服务给我？效果图如下：
基本架构：
采用 ASP + Access
用下列脚本在需要统计的页面增加反向链接记录
<script language=javascript src="/lib/refadd.js"></script>
用下列脚本在需要显示的页面增加反向链接显示
<script language=javascript src="/lib/refcnt.js"></script>
数据库：
数据库只需要一张表即可
ID:整数
IP:字符串(255)
Agent：字符串(255)
To：字符串(255)
Name：字符串(255)
From：字符串(255)
Date：日期时间
其中"Name"字段的值是对 From 处理后的结果，比如 From="" 则Name="Google"
分析:
只需要简单一个 SQL 查询即可：
SELECT [NAME],COUNT(*) FROM [REFERRER] GROUP BY [NAME] ORDER BY COUNT(*) DESC"
如果需要，还可以加上必要的条件，比如显示访问次数大于3次的记录：
SELECT [NAME],COUNT(*) FROM [REFERRER] GROUP BY [NAME] HAVING COUNT(*)>3 ORDER BY COUNT(*) DESC"
基本功能：
反向链接记录
反向链接显示（支持多种参数）
文件列表：
lib/refadd.asp
lib/refadd.js
lib/refcnt.asp
lib/refcnt.js
lib/refcon.asp
lib/images/percent.gif
dat/refdb.mdb
源代码：
由于 CSDN 不提供文件下载功能，所以我还要找一个地方上传源代码，不知道哪里有，各位同仁请告知道
