Next.js strips the router-internal headers (RSC, next-router-prefetch) before the request proxy runs, so prefetch detection based on them never fired: link prefetches were counted as page views. A page view is now a browser navigation, identified by the standard sec-fetch-dest: document header, which survives into the proxy. Prefetch payloads, subresource fetches and metadata-less clients are skipped as non-navigation requests.

/**

* Server request shell. Reads the incoming request once, classifies it via

|
* response. All analytics happen server-side; no tracking script ships to
|
|
* the browser.

|
* Page views are browser navigations (`sec-fetch-dest: document`).
|
|
* Router-internal headers (RSC, next-router-prefetch) are stripped by the

|
* server before this shell runs and cannot be used here.
