Chrome started partitioning the cache a couple years ago to mitigate timing attacks, so there's no network savings anymore when a bunch of sites all link to the same jQuery cdn entry.

I believe Safari has been doing it since 2013.

Someone did tests on it before this and found that with how many versions and cdn sources there are, your exact jquery is almost never in the cache.

Really proves the point that knowledge will atrophy. As a dev you need to invest in evergreen skills as well as trivia.

Fair enough. But it is still cached for your site.

jQuery is not unique in being cacheable
