XSS Homepage framework - Service - Proxy Class?

Dear all,

We would like to customize the resource links in the XSS Homepage framework.

In order to do this, I believe we can achieve this by using the Proxy class (Service definition in IMG).

The service must pass additional (dynamic) parameters to the resource.

The information for this proxy service field in SAP:

"Use this field if you want to influence the behavior of the service using your own code. To do this, you need to create a class that implements the IF_XSS_SER_PROXY_SERVICE interface."

Is there any additional information how to achieve this?

Kind regards,

Noel
