asp.net网站环境下编辑web.config文件，加入以下代码，可实现三个不同网站（带www和不带www）跳转到同一网站，即多域名重定向。

<system.webServer> 
<!--重定向 域名 开始-->
    <rewrite>
      <rules>
        <rule name="a0001 301 Redirect" stopProcessing="true">
          <match url=".*" />
          <conditions>
            <add input="{HTTP_HOST}" pattern="^a0001.com$" />
          </conditions>
          <action type="Redirect" url="http://www.d0004.com/{R:0}"
          redirectType="Permanent" />
        </rule>

        <rule name="www a0001 301 Redirect" stopProcessing="true">
          <match url=".*" />
          <conditions>
            <add input="{HTTP_HOST}" pattern="^www.a0001.com$" />
          </conditions>
          <action type="Redirect" url="http://www.d0004.com/{R:0}"
          redirectType="Permanent" />
        </rule>

        <rule name= "b0002 301 Redirect" stopProcessing="true">
          <match url=".*" />
          <conditions>
            <add input="{HTTP_HOST}" pattern="^b0002.com$" />
          </conditions>
          <action type="Redirect" url="http://www.d0004.com/{R:0}"
          redirectType="Permanent" />
        </rule>

        <rule name="www b0002 301 Redirect" stopProcessing="true">
          <match url=".*" />
          <conditions>
            <add input="{HTTP_HOST}" pattern="^www.b0002.com$" />
          </conditions>
          <action type="Redirect" url="http://www.d0004.com/{R:0}"

          <action type="Redirect" url="http://www.d0004.com/{R:0}"
          redirectType="Permanent" />
        </rule>

        <rule name="www b0002 301 Redirect" stopProcessing="true">

          redirectType="Permanent" />
        </rule>       
      </rules>
    </rewrite>
    <!--重定向 域名 结束-->
  </system.webServer>
