Shadow endpoints runs when going back to a page

[kenfoo]

Hi

I have a large list of items in Page [A].
The list of items is provided by the page's shadow endpoint.
The page will store the shadow endpoint in a local store.

Clicking on an item in this list brings the user to Page [B] where I show details of the selected item.

Now if hit the browser back button, I go back to Page [A].
However I notice that the browser performs a fetch request to __data.json to retrieve the props again for page [A] rendering.

Since the list is large, I'm trying to avoid refetching this list from the endpoint when navigating back to Page [A] when the user hits the browser back button.

Is there a way to avoid this fetch request when going back to this page, since I already have the data in my local store?
