windows2008+iis7(windows2012+iis8)系统通过web.config实现301

将以下规则复制到记事本内，保存为web.config（注意abc1.com、abc2.com替换为自己的域名）上传到网站根目录。

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <system.webServer>
        <rewrite>
            <rules>
                <rule name="301Redirect" stopProcessing="true">
                    <match url="(.*)" />
                    <conditions logicalGrouping="MatchAny">
                        <add input="{HTTP_HOST}" pattern="^abc1.com$" />
                        <add input="{HTTP_HOST}" pattern="^abc2.com$" />
                    </conditions>
                    <action type="Redirect" url="http://www.abc1.com/{R:0}" redirectType="Permanent" />
                </rule>
            </rules>
        </rewrite>
    </system.webServer>
</configuration>
