Custom extension REST API PUT/POST

[davidcodes]

Our dev team recently deployed a custom dll security implementation: https://github.com/Microsoft/Reporting-Services/tree/master/CustomSecuritySample

In our implementation, we're utilizing MemoryCache to store catalog data locally. However, we're unable to find the appropriate location to trigger a cache refresh whenever a user performs CRUD on any catalog items. 

Thoughts on where we might begin to look? As of right now, we're only seeing the point that PowerBI is requesting user info (i.e., we can see the URI and that it is a PUT/POST request). Consequently, we know that an action is happening, but we need to go 1-2 levels up the call chain to put an async/await and trigger a cache refresh if the PUT/POST is successful. We just don't know where to look.

Any help is greatly appreciated!
