Question on Keep-Alive header

[dadah89]

hi! Have a question on the Keep-Alive header.

I see in https://github.com/drbrain/net-http-persistent/blob/master/lib/net/http/persistent.rb#L943 that the header is set to a value (30 by default), so it'll send a header like Keep-Alive: 30.

But looking at the specification for the Keep-Alive header looks like it expects to be set with directives (e.g. timeout=30) instead of a number:

• https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Keep-Alive#directives
• https://www.rfc-editor.org/rfc/rfc2068.html#section-19.7.1.1
• https://tools.ietf.org/id/draft-thomson-hybi-http-timeout-01.html#rfc.section.2

Is that conclusion correct? Or am I mixing up things and not looking at the correct references docs?

Thanks!
