本版本不修改数据库，只修改了4个文件，并支持静态页模式！
效果
引用通告地址: trackback.asp?tbID=JNKRQOF8&key=JOKNPNKOQPMPPMC0
具体安装方法如下:
===========================================================
文件trackback.asp
查找
tbID = CheckStr(Request.QueryString("tbID"))
替换成
tbID = Decrypt(CheckStr(Request.QueryString("tbID")))
查找
If Not (IsInteger(Request.QueryString("tbID")) AND IsInteger(Request.QueryString("logID"))) Then
替换成
If Not IsInteger(Decrypt(Request.QueryString("tbID"))) AND IsInteger(Request.QueryString("logID")) Then
查找
Where blog_ID="&logID&" AND tb_ID="&CheckStr(Request.QueryString("tbID"))
替换成
Where blog_ID="&logID&" AND tb_ID="&Decrypt(CheckStr(Request.QueryString("tbID")))
**有2处

演示到我的BLOG看。我网络很慢。请您忍耐。
没有修改过这4个文件的用户可以下载下面的覆盖即可。
================================================
使用静态页的需要到后台从新建立所有日记。
不知道还有那不对的。希望大家踊跃测试，拍砖。
