  • HTTP/2

    Quels impacts pour mon site WordPress

  • Cest quoi HTTP dj ??!

  • Sir Tim Berner Lee au CERN, 1994

  • Hypertext Transfer Protocol

    GET

    HTMLKikoo!

  • ARPANET

    World Wide

    Web

    HTTP 0.9

    HTTP/1.1

    HTTP /2

    1969 1991 1995 1999 2015

    SPDY

    La version simple...

  • Et a marche ?

  • V.11

    Tous les navigateurs modernes sont compatibles.

    V.42 V.45 V.34 V.9

  • Pas trop mal !

  • Mais seulement 6% des sites lutilisent. Profitez en !

  • Passez en SSL

  • Optimisations Sans HTTP/2 Avec HTTP/2

    Spriting

    Concatenation

    Sharding

    CDN ???

    Arrtez les optimisations classiques.

  • Avec leur CDN >> schma waterfall classique, 2.3s

  • Sans le CDN >> 1.8s, its 22% faster

  • Passez en SSL Arrtez les optimisations redondantes Migrez vers un hbergeur compatible

    Pour rsumer, avant le grand saut.
