url rewrite and clients android ios device browser issue

I have a reverse proxy address https://www.abc.com with the inbound rule:

<rules>
                <rule name="ReverseProxyInboundRule1" stopProcessing="true">
                    <match url="(.*)" />
                    <conditions>
                        <add input="{CACHE_URL}" pattern="^(https?)://" />
                    </conditions>
                    <action type="Rewrite" url="{C:1}://en.wikipedia.org/{R:1}" />
                </rule>
            </rules>

on the backend I have a site like https://en.wikipedia.org

If I browse to " https://www.abc.com" from mobile device like android or ios browser. I get an error "Too many redirects". From desktop browser it works fine.
