What information was incorrect, unhelpful, or incomplete?

Browsers seem to send Connection: keep-alive by default, even though that's the default in HTTP/1.1. Based on the text of the page, it would make sense for them to do so if they were sending a Keep-Alive header, but they're not.

What did you expect to see?

If there's a historical compatibility reason why browsers send this header, it'd be helpful to document that.

Do you have any supporting links, references, or citations?
