第十二章：SPDY
12.1 SPDY概念及背景java
爲何須要SPDY？SPDY 協議只是在性能上對 HTTP 作了很大的優化，其核心思想是儘可能減小鏈接個數，而對於 HTTP 的語義並無作太大的修改。具體來講是，SPDY 使用了 HTTP 的方法和頁眉，可是刪除了一些頭並重寫了 HTTP 中管理鏈接和數據轉移格式的部分，因此基本上是兼容 HTTP 的。express
SPDY相比HTTP有以下優勢：apache
SPDY多路複用，請求優化；而HTTP單路鏈接，請求低效bootstrap
SPDY支持服務器推送技術；而HTTP只容許由客戶端主動發起請求安全
SPDY壓縮了HTTP頭信息，節省了傳輸數據的帶寬流量；而HTTP頭冗餘，同一個會話會反覆送頭信息服務器
SPDY強制使用SSL傳輸協議，所有請求SSL加密後，信息傳輸更安全app
