使用nginx处理静态资源请求，其余交给node

　　由于项目后台使用的是node，然而node不适合对静态资源的处理，因为他的异步处理（事件轮询）机制，所以更擅长的是密集I/O型的应用，所以我就有了一个想法，使用nginx来做反向代理，当请求的是静态资源的时候，直接由nginx（监听80端口）自己处理并返回，其他非静态资源请求转发至node(8080端口)，由node来处理。下面是我的nginx配置文档，nginx安装请自行百度，大把资料啦~

　　配置解释：当请求是以（css, js, gif, jpg, jpeg, png, bmp, swf)结尾的时候则nginx直接拦截请求（上面源码中标红的部分），由nginx静态服务器直接返回静态资源，而如果不是的话则将请求转发到node服务（上面源码中标蓝的部分），由node来完成其余请求。
