  • Yes, every browser caches resources that multiple pages of the same site use, unless the site instructs them not too.

    It is also the case that almost every modern browser does not share those caches between different websites, to avoid providing a mechanism for them to share data. This means that for websites, it is no longer beneficial to use CDNs, if it ever was - in practice, it was also the case that only very few CDN resources were actually shared between different websites (since they all depended on different versions or different CDNs).
