Unfortunately, depends on the server. Node says this:

"Sending a 'Connection: keep-alive' will notify Node.js that the connection to the server should be persisted until the next request."

The article seems to confirm this behavior.

So clients have to account for non RFC compliant servers.

Are you sure about that? That seems to violate the http/1.1 RFC. I think the node.js docs are talking about http/1.0 there. http/1.1 uses the "Connection" header to indicate whether to persist the connection.
