@parser = Http::Parser.new(self)
end
def receive_data(data)
@parser << data
end
def on_message_begin
@headers = nil
@body = ''
end
def on_headers_complete(headers)

end
def on_body(chunk)
@body << chunk
end
def on_message_complete
p [@headers, @body]
end

parser = Http::Parser.new
parser.on_headers_complete = proc{ :stop }
offset = parser << request_data
body = request_data[offset..-1]
