Camel Undertow does not provide an option to use the producer as the "Host" header when bridging two http endpoints

<route>
            <from uri="undertow:http://localhost:8189"/>
            <log message="Source ${in.headers.Host}" />
            <to uri="undertow:http://localhost:8289"/>
        </route>
        <route>
            <from uri="undertow:http://localhost:8289"/>
            <log message="Target ${in.headers.Host}" />
        </route>
