What is exactly included in the notion browser-cache? Does the notion browser-cache include in itself:

  • cookies
  • web-site-data
  • browser-settings
  • history
  • bookmarks

Or the notion browser-cache includes only already resolved dns-names and certain list of already visited web-pages/urls?

  • The "browser cache" is typically anything the browser has encountered that it thinks may need in the future (for "convenience" or to generally speed up browsing) and thus often stores automatically. Of the items you list, perhaps only bookmarks and browser settings would be excluded, since they are typically added/altered by users, not the browser. Dec 17, 2021 at 11:15

The browser cache contains URL, contents and time. It does not contain the cookies, browser-settings, history or bookmarks, as these are stored in separate containers.

The following image of the cache metadata in Chrome is taken from the article View Cache data:

  • would it be correct if we say that superuser.com is a domain-name and url simultaneously?

  • @ccsann: No : superuser.com is a domain-name, but https://superuser.com is a URL. The domain is kept in a DNS cache, while the URL is kept in the browser's cache.

  • and the dns-cache is a file/s that is read by the locale dns-client ( dnsmasq or systemd-resolved )?
