>+        Currently when we navigate we check if there is a cross-origin top-level
>+        prefetch we can use for the navigation. The current solution uses the
>+        HTTP cache as a way to store the prefetch and to immediately use it for
>+        the navigation. However this solution fails in case the prefetch is not
>+        cacheable in the first place. Instead of this, skip storing in the HTTP
>+        cache and simulate a HTTP Cache entry to process the load.
