WHO AM I ?

MY DAY TO DAY WORK :

CLEVER CLOUD, MAKE YOUR

APP RUN ALL THE TIME

And learn a lot of things about your code, apps, and good/bad design…

KEEP YOUR APPS ONLINE. MADE WITH

NODE.JS, SCALA, JAVA, RUBY, PHP,

PYTHON, GO…

AND LEARN A LOT OF THINGS ABOUT

YOUR CODE, APPS, AND GOOD/BAD

DESIGN…

WHAT IS THE HTTP JOB ?

THE SPEC IS MADE OF OPTIONS

AND ABILITY TO EXTENDS

FASTER FASTER FASTER

// REQUESTS ?

HTTP PIPELINING

THE HACKS WE

ARE DOING

EVERYDAY

WITHOUT

THINKING TO

IMPROVE

PERFORMANCES

MULTIPLE DOMAIN NAMES FOR

MULTIPLES STREAMS

STATIC ASSETS DOMAIN NAME FOR FAT

COOKIES PROBLEM MANAGEMENT

COMET/WEBSOCKET/PULLING/SERVER

SENT ENVENT… BIDIRECTIONAL DATA

STREAMS HACKS

SO, WE NEED A NEW VERSION OF HTTP

WHO IS IN CHARGE ?

HTTPBIS

WORKING

GROUP

FIRST

HTTP/2

DRAFT IS

SPDY/3

DRAFT

BUILD ON SOMETHING

SO WHAT IS IN THE BOX ?

HTTP/2 IS A BINARY

PROTOCOL

COMPRESSION + SSL UNABLE

TO READ ANYTHING

WIRESHARK FOR ALL

PUT SOME STEAMS IN ONE

CONNECTION

STREAMS

~ 1 HTTP/1 REQUEST = 1 HTTP/2 STREAM

FRAMES

Content a.html #1

Content dog.gif #1

Content a.html #2

Content dog.gif #2

Content a.html #4

Content a.html #3

Content cat.gif #1

Content dog.gif #4

…

BINARY GOODNESS =>

FRAMES IS EASY

STREAMS PRIORITY

PUSH FROM THE SERVER A RESOURCE

TO THE CACHE

HEADERS

COMPRESSIONS

HPACK

*new RFC*

FOCUS ON WEB

PERFORMANCES

URL

CANNOT

CHANGE

HOW TO UPDATE THE

WEB ?

HTTP

&

HTTPS

NEGOCIATE

A

PROTOCOL

ELEVATION

HTTP/1 BUILD IN METHOD

Upgrade: header

Code 101 Switching

WORKFLOW

WORKFLOW

IT’S STILL SLOW

ENCRYPT

THE WEB :

TLS

NEGOTIATE THE PROTOCOL IN

THE SAME TIME OF ENCRYPT

NEGOTIATION

NPN (CLIENT)

&

ALPN (SERVER)

IS IT FOR

REAL?

LOOKS LIKE

IP V6

ALL THE

GOODNESS OF

HTTP2 IN

YOUR HTTP1

APP FOR

NOTHING :-)

WHY IT’S

SO COOL?
