+## Aspects of Blazor WebAssembly caching apply to Blazor Web Apps
+
+Blazor bundle caching and HTTP caching guidance in the *Blazor WebAssembly* node focus on standalone Blazor WebAssembly apps, but several aspects of client-side caching in these articles also apply to Blazor Web Apps that adopt Interactive WebAssembly or Interactive Auto render modes. If a Blazor Web App that renders content client-side encounters a static asset or bundle caching problem, see the guidance in these articles to troubleshoot the problem:

 Common problems that negatively impact the user upgrade experience include:
 
 * **Incorrect handling of project and package updates**: This happens if you don't update all of the app's deployed projects to use the same major framework version or if you use packages from a previous version when a newer version is available as part of the major upgrade.
-* **Incorrect configuration of caching headers**: HTTP caching headers control how, where, and for how long the app's responses are cached. If headers aren't configured correctly, users might receive stale content.
+* **Incorrect configuration of caching headers**: HTTP caching headers control how, where, and for how long the app's responses are cached. If headers aren't configured correctly, users might receive stale or mismatched files. This includes [Blazor bundle assets caching](xref:blazor/host-and-deploy/webassembly/bundle-caching-and-integrity-check-failures), where server caching headers must be properly set to avoid caching problems on the client.
 * **Incorrect configuration of other layers**: Content Delivery Networks (CDNs) and other layers of the deployed app can cause issues if incorrectly configured. For example, CDNs are designed to cache and deliver content to improve performance and reduce latency. If a CDN is incorrectly serving cached versions of assets, it can lead to stale content delivery to the user.

 ### Verify the presence of correct caching headers
 
-The correct caching headers should be present on responses to resource requests. This includes `ETag`, `Cache-Control`, and other caching headers. The configuration of these headers is dependent on the hosting service or hosting server platform. They are particularly important for assets such as the Blazor script (`blazor.webassembly.js`) and anything the script downloads.

 Incorrect HTTP caching headers may also impact service workers. Service workers rely on caching headers to manage cached resources effectively. Therefore, incorrect or missing headers can disrupt the service worker's functionality.
