为了便于搜索引擎抓取(换句话就是假静态)，下面是URL ReWrite的规则，效果看我的chinadigger的链接地址。我目前的Rewrite规则：
[ISAPI_Rewrite]
# 3600 = 1 hour
CacheClockRate 3600
RepeatLimit 32
# Protect httpd.ini and httpd.parse.errors files

使用方法（将Wordpres安装在根目录）
去discuz.net的论坛下载Rewrite的压缩包，然后按照安装方法在IIS里面配置好Rewrite，用上面的规则覆盖httpd.ini中原来的内容，再到wordpress的后台，将选项的永久链接部分，使用自定义，然后在框框里面填写上面粗体部分的内容（两种选一种，其中# /post/%post_id%.html还不太完善），即可。
本文引用bluefeel所写的规则。原文中TAG编写有问题，我已经更改完毕，大家要注意写法，否则会影响其他IIS站点目录。
