最近的工作中频繁用到HTTPCLIENT这个类
先放上github的项目地址 https://github.com/gabriel/as3httpclient
原理就是利用socket模拟一个http链接来突破flash player的各种限制
由于是socket连接，所以跨域问题大家还是要好好注意下的
比如原先urlrequest中不能自定义的referer之类的
还有一个妙处就是原先的netstream是不能读取到流的数据，
有时候在流里会藏一些数据，这时候就用到这个类来解决了
这源码是搜索的时候翻到的国外技术，因为原链接已经流失，
俄罗斯战斗民族我又惹不起。。我只好在这里标明我是转载了 ＝。-
