When navigating back in the web viewer, the previous page reloads, causing slow load times. Is there a way to implement caching functionality similar to browsers, so that the cached page is displayed instead of reloading the entire page?
To speed up back navigation in your web viewer, implement caching. Client-side caching, using service workers (for PWAs), HTTP cache headers, or in-memory/local storage, is usually the best approach. Server-side caching, via reverse proxies or web server modules, is effective if you control the server. Be sure to handle cache invalidation and memory usage appropriately. The optimal strategy depends on your web viewer’s implementation and server access.
