Can someone explain why one DNS lookup was enough?

Can someone explain why one DNS lookup was enough?
- laumars 13y agoOne DNS lookup per domain name. And once you know the IP, there's little point looking it up again as it's not going to change in the milliseconds between HTTPS/SPDY requests.
- kalmi10 13y agofrom the article: "In Chrome there was only a single TCP connection and a single DNS lookup needed despite the presence of three domains." See cloudflare's answer to my original question.

- kalmi10 13y agoInteresting. Does this mean that Chrome actually issues those requests over that single SPDY connections on the assumption that it belongs there without first waiting for the confirmation from the DNS servers? (And then not using the corresponding responses until it gets the DNS confirmations?)
