Looks great! The one thing I think that remains is how we align the browsers ability to cache the requests. One part of this whole solution was a special ServiceWorker that caches the resolution of the URI's so that the browser can effectively cache the requests when able, like with images for example. This saves on bandwidth significantly in presigned url use cases with normal usage within DataManager -> QuickView. The ServiceWorker only acted on url's that had the word presign in it, but now I see the endpoint is resolve instead. This will mean that the previous behaviour will not work completely, so we will have to update the ServiceWorker accordingly as well. I can make that change on this PR.

@bmartel great point! Thank you for the fix! /resolve now makes more sense. I kept /presign for backward compatibility.
