Bug 1802730 [wpt PR 37174] - [No-Vary-Search] Add No-Vary-Search logic to prefetch cache, a=testonly
Automatic update from web-platform-tests [No-Vary-Search] Add No-Vary-Search logic to prefetch cache Add logic to keep track of No-Vary-Search response data in prefetch cache and use it to make decisions to use existing prefetched response on new navigation. Bug: 1378075 Change-Id: Ie299308ead2b369b899c17d4a33a64588376a07d Fuchsia-Binary-Size: Size increase is unavoidable.
