Learn Performance - Prefetch and Prerender

On Chromium-based browsers, it is also possible to prefetch resources or documents using speculation rules. This page contains speculation rules to prefetch the document 3-prefetch.

Go to prefetched page

Similarly to the previous demo, if you observe the network tab, you should notice that the document is prefetched.

In the network panel above, the prefetched document 3-prefetch is downloaded with the Lowest priority.

    "prefetch": [
      {
        "source": "list",
        "urls": ["/3-prefetch"]
      }
    ]
  }
