Cookie Vary Test

This page sets Vary: Cookie on every response. The page cache sees this header and emits a s-vary-cookie skip — it refuses to cache the response unless the matching rule explicitly opts in via varyOnCookies.

<script>
  import { files } from './files.ts';

  const sources = await loadSources(files);
</script>

<p>Check the response headers: <code>Vary: Cookie</code> is set by the route handle.</p>
