- * A class implementing the `cachedResponseWillBeUsed` lifecycle callback.
- * This makes it easier to add in support for used cached responses to fulfill
- * requests with `Range:` headers.
+ * The range request plugin makes it easy for a request with a 'Range' header to
+ * be fulfilled by a cached response.
  *
- * If an incoming request does contain a `Range:` header, then the appropriate
- * subset of the cached body will be returned as part of a HTTP 416 response.
- *
- * If the incoming request does not contain a `Range:` header, then the cached
- * response will be used as-is.
+ * It does this by intercepting the `cachedResponseWillBeUsed` plugin callback
+ * and returning the appropriate subset of the cached response body.
