以下方式采取的是IIS: “URL 重写” 或者 “URL Rewrite” 模块

替换或增加网站根目录文件：web.config。

指定1个域名跳转

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <system.webServer>
        <rewrite>
            <rules>
                <rule name="HTTPS" stopProcessing="true">
                    <match url="^(.*)$" ignoreCase="false" />
                    <conditions logicalGrouping="MatchAll">
                        <add input="{http_host}" pattern="^gworg.com" />
                    </conditions>
                    <action type="Redirect" url="https://www.gworg.com/{R:1}" redirectType="Permanent" />
                </rule>
            </rules>
        </rewrite>
    </system.webServer>
</configuration>

指定多个域名跳转HTTPS方式

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <system.webServer>
        <rewrite>
            <rules>
                <clear />
                <rule name="Gworg" stopProcessing="true">
                    <match url="^(.*)$" />
                    <conditions>
                        <add input="{HTTPS}" pattern="^OFF$" />
                        <add input="{HTTP_HOST}" pattern="^www\.gworg\.com$|^gworg\.com$" />
                    </conditions>
                    <action type="Redirect" url="https://{HTTP_HOST}/{R:1}" />
                </rule>
            </rules>
        </rewrite>
    </system.webServer>
</configuration>

指定多个域名跳转HTTPS方式（备用代码，可能无效）

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <system.webServer>
        <rewrite>
            <rules>
                <clear />
                <rule name="https" stopProcessing="true">
                    <match url="(.*)" />
                    <conditions logicalGrouping="MatchAll" trackAllCaptures="false">
                        <add input="{HTTPS}" pattern="^OFF$" />
                        <add input="{HTTP_HOST}" pattern="^pay2\.gworg1\.cn$|^pay\.gworg2\.net$|^pay2\.gworg3\.org$|^pay3\.gworg4\.com$|^pay2\.gworg5\.org$|^pay\.gworg6\.cn$" negate="true" />
                    </conditions>
                    <action type="Redirect" url="https://{HTTP_HOST}/{R:1}" />
                </rule>
            </rules>
        </rewrite>
    </system.webServer>
</configuration>
