这是小弟写的一个代理服务器的方法.clientSock监听localhost的请求(其实就是用localhost作代理,有什么就传回什么,很简单没什么实际意义的代理),serverSock获取服务器的字节.然后这个DoRequest就是总的方法如果网页是一口气把byte都传送回来的话,网页显示没问题,但问题是,如果网页的Transfer-Encoding是chunked的话,这个方法就不行了.POST也貌似不能用...那位大大能够提供一个解析chunked的C#代码呢？最好是能够直接用在我最下面外边的else里面的（因为是草稿，所以会有些没什么意义的代码，抱歉了） public void DoRequest()
