Implement stale-while-revalidate (SWR) feature for SPA applications using clientLoader

**Description:**

To enhance user experience and improve caching functionality in SPA applications, I propose implementing a feature based on the "stale-while-revalidate" (SWR) caching strategy. This would allow the `clientCache` to serve stale data from the cache while revalidating it in the background. The SWR approach is particularly beneficial for SPAs where immediate responses are critical and data freshness can be updated seamlessly.

**Use Case:**

For a SPA displaying a list of items, users can instantly view cached data while the app silently updates the list in the background. This ensures a balance between performance and data freshness.

**Benefits:**

- Improved perceived application speed.
- Enhanced user experience due to consistent data availability.
- Simplified cache management with automatic revalidation.
