      if the expires value is in the past, then obviously the file is outdated

      last modified in the future? doesn’t make sense, eh?

      see MIME-Type. it’s like the difference between “this is a door” and “this is a dog”

      the data you have shown are HTTP/1.x data, thus they are sent by the server (HTML uses the <meta> elements for that)
