end

attribute　String

attribute　String | Array(String) | Nil

the request protocol, usually empty, but occasionally "websocket" or "webtransport". In HTTP/1, it is used to request a connection upgrade, and in HTTP/2 it is used to indicate a specfic protocol for the stream.

attribute　Proc

returns　Peer | Nil

def peer
	nil
end

def call(connection)
	connection.call(self)
end

def send_interim_response(status, headers)
	@interim_response&.call(status, headers)
end

yields　{|status, headers| ...}

The callback to be called when an interim response is received.

parameter　status　Integer

The HTTP status code, e.g. 100, 101, etc.

	if interim_response = @interim_response
		@interim_response = ->(status, headers) do
			block.call(status, headers)
			interim_response.call(status, headers)
		end
	else
		@interim_response = block
	end
end
