TWebClientDataset

In the documentation I cannot find what and how the server side should be implemented. What kind of request are done? What should the answer be?
Are there any examples that show a roundtrip:
Data request from client to server
Reply,from the server
Handling of that reply by the TWebClientDataset.

TIA,
Peter

A TWebClientDataSet is designed to be flexible to be used together with different back-end implementations.
You can feed the data as an array via WebClientDataSet.Rows: TJSArray and you can perform insert, delete, update operations on records from the OnUpdateRecord event.
Typically, you perform REST API requests to your backend to get the data to feed to Rows and the same for updating records from the TWebClientDataSet to the server.
