As per the sample the dynamicUri endpoint is always uses manifest server(first index of servers info array) as proxy base.
How do I intercept this call or make it use of an auxiliary server instead of manifest server?
In our architecture, we had decoupled UI service and plugin backend service as different services. I mean the manifest server just serves static UI related resources like .js,.html,.json running on a spring boot based tomcat and no rest implementation.
Actual backend REST API server will be registered as an Auxiliary Server and all HTTP/REST calls will be pointing to it. In this scenario, the dynamicUri endpoints also needed to be calling auxiliary server instead of manifest server.
How could we do this?
This is currently not possible - we are planning to add support for it in a future release. Perhaps using the manifest server as a proxy could be a temporary solution for you.
