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：

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.webServer>
<rewrite>
<rules>
<rule name="Redirect（命名）" stopProcessing="true">
<match url="^（要重定向的页面）" />
<conditions logicalGrouping="MatchAll" trackAllCaptures="false" />
<action type="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：

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.webServer>
<rewrite>
<rules>
<rule name="Redirect" stopProcessing="true">
<match url="^abc/001.html" />
<conditions logicalGrouping="MatchAll" trackAllCaptures="false" />
<action type="Redirect" url="http://" />
<rule name="Redirect2" stopProcessing="true">
<match url="^abc/002.html" />
<conditions logicalGrouping="MatchAll" trackAllCaptures="false" />
<action type="Redirect" url="http://" />
</rule>
</rules>
</rewrite>
</system.webServer>
</configuration>
//注意：多个页面跳转时，rule name不能相同

3.整站301跳转，代码如下

<?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="^需要转的域名$" />
</conditions>
<action type="Redirect" url="http://要转到的域名/{R:0}"
redirectType="Permanent" />
</rule>
</rules>
</rewrite>
</system.webServer>
</configuration>
