web.config不带www301到带www的书写规则

具体的规则是这样的

<?xml version=”1.0″ encoding=”UTF-8″?>
<configuration>
<system.webServer>
<rewrite>
<rules>
<rule name=”WWW Redirect” stopProcessing=”true”>
<match url=”.*” />
<conditions>
<add input=”{HTTP_HOST}” pattern=”^htheavy.com$” />
</conditions>
<action type=”Redirect” url=”http://www.htheavy.com/{R:0}” redirectType=”Permanent” />
</rule>
</rules>
</rewrite>
</system.webServer>
</configuration>

写到web.config里面，记得把中间的网址换成自己的网址，上传网站根目录就可以了自动生效了！
