要實(shí)現(xiàn)IIS上的這種域名重定向，你可以使用URL重寫模塊來配置重定向規(guī)則。以下是一個基本的web.config配置示例，它實(shí)現(xiàn)了你的需求：

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
 <system.webServer>
        <rewrite>
            <rules>
               <rule name="301Redirect-1" stopProcessing="true">
                  <match url="(.*)" />
                  <conditions logicalGrouping="MatchAny">
                     <add input="{HTTP_HOST}" pattern="^wan-qi\.cn$" />
                  </conditions>
                  <action type="Redirect" url="https://www.wan-qi/{R:0}" redirectType="Permanent" />
               </rule>

               <rule name="Redirect to https" stopProcessing="true">
                    <match url="^(.*)$" ignoreCase="false" />
                    <conditions logicalGrouping="MatchAll">
                        <add input="{HTTP_FROM_HTTPS}" pattern="^on$" negate="true" />
                    </conditions>
                    <action type="Redirect" url="http://m.dewina.cn/{R:1}" redirectType="Permanent" />
               </rule>
            </rules>
        </rewrite>
    </system.webServer> 
</configuration>
