URL Normalizer

Configure a No-Vary-Search response header and see which of a list of URLs would share the same cache entry. Chrome 135 extends this to the HTTP disk cache (it already worked in the prefetch cache). The normalizer shows the canonical cache key after stripping ignored or reordered params.

checking No-Vary-Search disk cache support…

No-Vary-Search tells the cache which query parameters don't affect the response body. With params you can ignore specific keys (e.g. UTM parameters); with key-order you signal that parameter order doesn't matter. Chrome 135 extends this from the prefetch cache to the full HTTP disk cache, so repeated navigations benefit too.
