里面的这一段代码

<system.webServer>
	<rewrite>
		<rules>
			<rule name="WWW Redirect" stopProcessing="true">
				<match url=".*" />
				<conditions>
					<add input="{HTTP_HOST}" pattern="^onestopweb.cn$" />
				</conditions>
				<action type="Redirect" url="http://www.onestopweb.cn/{R:0}" redirectType="Permanent" />
			</rule>
		</rules>
	</rewrite>
</system.webServer>

 

解决了主域名和www域名同一站点301重定向问题，例如输入 baidu.com，则跳到 www.baidu.com。有利于做SEO优化。提高www域名的访问量，提高www域名的排名。
