HTTP 協議是目前流行的Web 技術的主要協議，是Web 瀏覽器和Web 服務器之間進行通信的基礎。本文首先對嵌入式系統從整體上進行了簡析，說明了嵌入式系統不同于通用型計算機系統的特點和嵌入式系統應用的廣泛性。然后從協議的角度出發論述HTTP協議。最后介紹了一個基于嵌入式Web 技術的AllLightSYS 系統的設計與實現，重點闡述嵌入式服務器軟硬件部分的設計思想和體系架構，并對關鍵技術進行了詳細的介紹。

The method of designing an AllLightSYS based on embedded Web HE Xiao-Li ZHANG Xi-Huang (College of Information Engineering of Southern Yangtze University Jiangsu Wuxi 214122) Abstract HTTP is the key protocol of World Wide Web which is most popular today, and is the basis on which communicating between Web browser and Web server bases. This papers starts with a brief analysis of the embedded system on the whole, describing some properties of embedded systems and the universality of embedded applications. Then HTTP protocol were discussed . At the last, we propose the method of an embedded server based on embedded World Wide Web ——AllLightSYS, the hardware parts and software parts of the embedded server and the key technology were described in detail .
