    "Tim Kaldec et Yoav Weiss se sont donc inspirés de ce mécanisme [Content Security Policy], pour le transposer au sujet de la performance web, en proposant un nouvel en-tête HTTP (Content Performance Policy) permettant de déclarer précisément le degré de compatibilité d'une page avec certaines bonnes pratiques de performance web. À la charge ensuite du navigateur web, de forcer l'application des bonnes pratiques annoncées qui ne seraient pas respectées par l'éditeur."

    Use this file to prevent your computer from connecting to selected internet hosts. This is an easy and effective way to protect you from many types of spyware, reduces bandwidth use, blocks certain pop-up traps, prevents user tracking by way of "web bugs" embedded in spam provides partial protection to IE from certain web-based exploits and blocks most advertising you would otherwise be subjected to on the  internet.

webperf JavaScript document.write

    Alternative à Ghostwriter ou ControlJS : permet de reporter le document.write de certains scripts à plus tard dans le flux de chargement de la page, afin de ne pas retarder le Load. L'intérêt de la solution est qu'elle ne perturbe quasiment pas le script original, ce qui en facilite grandement la maintenance.
