The Auth0 React SDK handles grant and protocol details, token expiration and renewal, as well as token storage and caching. This tells react to instantiate a new component every time the image's x coordinate changes and without cache that means re-downloading the image (try moving only vertically and you'll see no reload).

This library is powerful for a couple of reasons: The library comes with a profiler which tells you which components are most expensive on the server. I can reproduce the behavior you describe: ĭisabling cache does cause the image to re-downloaded every time. Walmart Labs put out a library called electrode-react-ssr-caching which is easy to use to cache your server-side renders.
