本发明属于网络通信技术领域，涉及一种网站的加速方法及系统，特别是涉及一种基于内容分发网络的网站加速方法及系统。
背景技术
CDN(Content Delivery Network，即内容分发网络)是一种新型网络构建方式，它是为了能在传统的IP网发布宽带丰富媒体而特别优化的网络覆盖层。从广义的角度，CDN代表了一种基于质量与秩序的网络服务模式。简单地说，内容分发网络(CDN)是一个经策略性部署的整体系统，包括分布式存储、负载均衡、网络请求的重定向和内容管理4个要件，而内容管理和全局的网络流量管理(Traffic Management)是CDN的核心所在。通过用户就近性和服务器负载的判断，CDN确保了内容以一种极为高效的方式为用户的请求提供服务。总的来说，内容服务基于缓存服务器，也称作代理缓存(Surrogate)实现。代理缓存位于网络的边缘，距用户仅有“一跳”(Single Hop)之遥。同时，代理缓存是内容提供商源服务器(通常位于CDN服务提供商的数据中心)的一个透明镜像。这样的架构使得CDN服务提供商能够代表他们客户，即内容供应商，向最终用户提供尽可能好的体验，而这些用户是不能容忍请求响应时间有任何延迟的。
CDN的基本思路是尽可能避开互联网上有可能影响数据传输速度和稳定性的瓶颈和环节，使内容传输的更快、更稳定。通过在网络各处放置节点服务器所构成的在现有的互联网基础之上的一层智能虚拟网络，CDN系统能够实时地根据网络流量和各节点的连接、负载状况以及到用户的距离和响应时间等综合信息将用户的请求重新导向离用户最近的服务节点上。其目的是使用户可就近取得所需内容，解决Internet网络拥挤的状况，提高用户访问网站的响应速度。
随着CDN的普及，越来越多的网站选择采用CDN加快网站的访问速度，随之也出现越来越多的专业CDN加速服务商。每个CDN厂商都有各自的加速技术、硬件配备和加速效果，网站面临的CDN厂商选择也越来越多，越来越难以抉择。
通常情况下，网站采用的CDN加速方案包括：
1、企业自行选择市面上口碑较好的CDN厂商做加速测试服务。
2、由所选择的CDN厂商提供域名别名，并在网站所属DNS服务器上做域名别名。
3、该所选择的CDN厂商为网站提供CDN加速服务，并提供全国区域的加速前后效果对比数据。
现有的网站CDN加速方案存在以下弊端：
1、全国各地都做CDN加速，个别地区用户较少，暂无需该服务，造成支出浪费。
2、对于同一网站不同域名下的资源，一家或多家CDN商家为同一个地区服务，未必能为每个地区提供最佳加速效果。
3、对于同一网站相同域名下的不同资源，一家或多家CDN商家未必能为每个地区提供最佳加速效果。
4、对于同一网站相同域名下的相同资源，一家CDN商家未必能为每个地区提供最佳加速效果。
