Hmm, that's good catch - thanks. HTTP 1.0 didn't explicitly specify anything around persistent connections, so in practice you can add Keep-Alive header and hop

Hmm, that's good catch - thanks. HTTP 1.0 didn't explicitly specify anything around persistent connections, so in practice you can add Keep-Alive header and hope that the server will respect it. By comparison, HTTP 1.1 defaults to persistent always and requires a "Connection: close" header to indicate otherwise.
