1、先在服务器上安装这个插件：
http://www.isapirewrite.com/download/isapi_rwl_x86_0059.msi
2、然后给IIS添加ISAPI筛选器 （这步应该是安装后自动生成，不需要操作，只需要检查一下是否存在就行）
3、最后修改httpd.ini(在ISAPI_Rewrite安装目录下)
添加以下代码：
[ISAPI_Rewrite]
# 3600 = 1 hour
CacheClockRate 3600
RepeatLimit 32
# Protect httpd.ini and httpd.parse.errors files
# from accessing through HTTP
DZ的静态规则（这句话不要，只是说明）

RewriteRule ^(.*)/profile-(username|uid)-(.+?)\.html$ $1/viewpro\.php\?$2=$3
RewriteRule ^(.*)/space-(username|uid)-(.+)\.html$ $1/space\.php\?$2=$3
PW的静态规则（这句话不要，只是说明）
RewriteRule ^(.*)-htm-(.*)$ $1.php?$2
RewriteRule ^(.*)/simple/([a-z0-9\_]+\.html)$ $1/simple/index.php?$2
4、网站后台设置启用静态，OK
