The DELEGATE element specifies the Genero REST service in charge of all starting requests of the form /wa/r, /ja/r and /ws/r. It takes an attribute called service where you define the group and name of the Genero REST service.
<DELEGATE service="serName"> [ <AnyTag1> anyValue </AnyTag1> ] [ <AnyTag2> anyValue </AnyTag2> ] </DELEGATE>
All child elements are optional and are passed as parameters to the REST service if present. See Delegate the start of an application or service.
When working with a single sign-on solution, child elements of the DELEGATE element will be specific to the identity provider (IdP). You will need to add the appropriate tags to work with your IdP. These tags should be documented by your IdP.
