That should definitelly work, if you wan't to make the service more readable, you can also write the implicit component : 

&lt;model name="ProxySample"&gt;
    &lt;service name="HttpProxyService"&gt;
        &lt;inbound&gt;
            &lt;http:inbound-endpoint address="http://localhost:8787" synchronous="true"/&gt;
        &lt;/inbound&gt;

        &lt;bridge-component /&gt;

        &lt;outbound&gt;
            &lt;pass-through-router&gt;
                &lt;outbound-endpoint address="http://server2.xyz.com:8080#[header:http.request]" synchronous="true"/&gt;
            &lt;/pass-through-router&gt;
        &lt;/outbound&gt;
    &lt;/service&gt;
&lt;/model&gt;
