Redirect to another site but show the original URL in browser

Question

I need help with a question about URL Rewrite.
Currently the redirection rule below works correctly.

<rule name="test_redirect" stopProcessing="true">
    <match url="^(.*)$" />
        <conditions>
            <add input="{HTTP_HOST}" pattern="^name.domain.com$" />
            <add input="{HTTPS_HOST}" pattern="^name.domain.com$" />
        </conditions>
    <action type="Redirect" url="http://IP address/service" redirectType="Permanent" />
</rule>

Now what I need is that the browser's address bar still displays the original url.
(Example: "http://name.domain.com" redirects to "http://IP address/service" but the browser's address bar still displays "http://name.domain.com".)
So, I made the following configuration change:

<rule name="test_redirect" stopProcessing="true">
    <match url="^(.*)$" />
        <conditions>
            <add input="{HTTP_HOST}" pattern="^name.domain.com$" />
            <add input="{HTTPS_HOST}" pattern="^name.domain.com$" />
        </conditions>
    <action type="Rewrite" url="http://IP address/service" redirectType="Permanent" />
</rule>

But didn't it work:

• The page loaded with an error.
• The "/service" has been added to the original URL.
  Where is the error? Are there some configuration missing?
  Can anyone help me with this?
  Thanks.
• Firstly, I installed the ARR module: (https://www.iis.net/downloads/microsoft/application-request-routing).
• After the installation is complete, I opened it at the IIS server level, selected "Server Proxy Settings", and checked "Enable proxy".
• I changed "action type="Redirect" to "action type="Rewrite".
  The IIS version is 10.0.17763.1 on Windows Server 2019 Datacenter.

Among the iis server variables, there is no server variable {HTTPS_HOST}.

Please remove this from <conditions> and try again.

<add input="{HTTPS_HOST}" pattern="^name.domain.com$" />
