Control of requisitions.

Control of requisitions.

A doubt with WebCore + XData.
Example:
1-) Requesting a product entity from XData that returns a list with 100 items.

Is there any way that after the first request if I need to make new requests I validate if there are changes so I don't ask for the list again and so use the list I already have?

The intention is only to remove the weight of the server as much as possible

Maybe this can help?
