首先是要安装伪静态模块,具体安装方法另行百度搜索.
安装完后,在网站根目录的web.config文件填入下面代码即可.
白名单一行不够可以复制一行,表示只允许www.orsoon.com.com的来源才显示jpg,gif资源.
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.webServer>
<rewrite>
<rules>
<rule name="Prevent hotlinking">
<match url="^.*\.(jpg|gif)$" ignoreCase="true" />
<conditions>
<add input="{HTTP_REFERER}" pattern="http://www.orsoon.com/.*" negate="true" />
</conditions>
<action type="Rewrite" url="/img/logo.png" />
</rule>
</rules>
</rewrite>
</system.webServer>
</configuration>
