摘　　要：通过对目前互联网流量的抽样分析,图片占全球所有互联网流量的比重超过50%,几乎每个网页中都会产生非常可观的图片流量。并且随着日益增长的Web流量以及迅猛发展的移动互联网,人们需要一种比传统图片传输方式更加优化的方式来解决日益严重的性能问题。基于这种背景,文中给出一种将服务器图片缓存在HTTP页面中的离线加速下载方案,可以有效地提高图片的传输效率,加快页面的加载速度,在不改变现有Web框架基础的情况下使用户获得更好的用户体验。Through the sampling analysis of present Internet traffic,image flow accounts for over 50% of all the global Internet traffic. Al-most every web page will produce a considerable flow of images. Because of the increasing Web traffic and the rapid development of mo-bile Internet,people need a better optimization approach than the traditional image transmission to solve the increasingly serious perform-ance issues. Based on this background,propose a design scheme for the offline download acceleration that server images are cached in the HTTP page in this paper. Without changing the current Web framework,this scheme can effectively improve the efficiency of the trans-mission of the picture,speeding up page loading speed,and let users get a better user experience.
