web怎么做301跳转

web做301跳转的方法：

1.例如在web.config文件中的301格式：

<?xmlversion="1.0"encoding="UTF-8"?>
<configuration>
<system.webServer>
<rewrite>
<rules>
<rulename="Redirect（命名）"stopProcessing="true">
<matchurl="^（要重定向的页面）"/>
<conditionslogicalGrouping="MatchAll"trackAllCaptures="false"/>
<actiontype="Redirect"url="（重定向到的页面）"/>
</rule>
</rules>
</rewrite>
</system.webServer>
</configuration>

2.多个页面跳转，代码如下：

<?xmlversion="1.0"encoding="UTF-8"?>
<configuration>
<system.webServer>
<rewrite>
<rules>
<rulename="Redirect"stopProcessing="true">
<matchurl="^abc/001.html"/>
<conditionslogicalGrouping="MatchAll"trackAllCaptures="false"/>
<actiontype="Redirect"url="http://"/>
<rulename="Redirect2"stopProcessing="true">
<matchurl="^abc/002.html"/>
<conditionslogicalGrouping="MatchAll"trackAllCaptures="false"/>
<actiontype="Redirect"url="http://"/>
</rule>
</rules>
</rewrite>
</system.webServer>
</configuration>
//注意：多个页面跳转时，rulename不能相同

3.整站301跳转，代码如下

<?xmlversion="1.0"encoding="UTF-8"?>
<configuration>
<system.webServer>
<rewrite>
<rules>
<rulename="WWWRedirect"stopProcessing="true">
<matchurl=".*"/>
<conditions>
<addinput="{HTTP_HOST}"pattern="^需要转的域名$"/>
</conditions>
<actiontype="Redirect"url="http://要转到的域名/{R:0}"
redirectType="Permanent"/>
</rule>
</rules>
</rewrite>
</system.webServer>
</configuration>
