Cache busting
Cache busting is the practice of changing a resource’s cache identity or invalidating cached data to force retrieval or execution of updated content.
Pro ASP.NET Core 7, Tenth Edition
A cache-busting value is a changing resource identifier component that causes clients to retrieve a new version instead of using a stale cached file.
- How it is used
- Keeps deployed static files current for clients while retaining the benefits of caching.
- How deep it goes
- Explains the stale-cache problem and shows generated version URLs, without detailing checksum generation.
- Examples
- Shows versioned jQuery and skyline-image URLs generated from elements in a shared Razor layout.
- What you can do after
- Apply it via ASP.NET Core tag helpers by setting asp-append-version on script and img elements and inspecting rendered URLs.

ASP.NET Core in Action, 3e
Cache busting is a technique that changes a resource's cache identity when its contents change so clients retrieve the latest version.
- How it is used
- Keeps static assets cached for performance while requesting changed images, stylesheets, and scripts immediately.
- How deep it goes
- Defines manual query strings and explains content hashing with the Append Version Tag Helper, but does not detail caching internals.
- Examples
- Uses a JavaScript file, manual version values, and an asp-append-version-generated URL as concrete examples.
- What you can do after
- Apply it via the Append Version Tag Helper to version linked, scripted, and image assets automatically.
