TONIGHT • DNS: What Does 72.26.203.99 Mean? • HTTP: Its Just Text! • MVC: The Way of Web Apps • Recipes: Login and Email • Scaling: More, Smaller, Faster
DNS What Do Those Numbers Mean?
DOMAIN NAMING SERVICE • Computers are bad with names, prefer numbers • People are bad with numbers, prefer names • DNS bridges the gap
• You type http://xkcd.com in a browser • Your computer asks its local DNS server where xkcd.com is • That DNS server asks an authoritative server • Then relays the IP address (72.26.203.99)
DOMAIN NAMING SERVICE where is xkcd.com? your computer DNS server
DOMAIN NAMING SERVICE where is xkcd.com? where is xkcd.com? your computer DNS server authoritative DNS server
