If you add more than one grid on a page, which refers to the same Controller & Action name, then it was sharing the single cookie name & all the data like Filters/Sorts etc will be shared across both the grid. Since we are persisting the data in cookie, the same filter/sort may be applied to the grid on another page in application if they are pointing to same Controller/Action.

Eg.

Scenario 1:
Page 1 -> Grid 1 -> Contoller: Home, Action: GetData
Page 1 -> Grid 2 -> Contoller: Home, Action: GetData

Scenario 2:
Page 1 -> Grid 1 -> Contoller: Home, Action: GetData
Page 2 -> Grid 2 -> Contoller: Home, Action: GetData

We need a way to uniquely distinguish the grid on same or different page within application. Provide an option to pass GridIdentifier as param in request which will uniquely identify the grid.
