这篇文章是讲如何做一个论坛灌水机，针对某个大型房地产论坛测试通过，那是一个基于jive3的论坛，假如论坛加入了图片认证登陆，本程序将失去作用。
本程序使用了HTTPClient包，下载地址：
http://www.innovation.ch/java/HTTPClient/
灌水机原理很简单，就是分析论坛的表单，用自己的程序模拟提交就可以了，
本文的目的在于介绍HTTPClient这个开源工具，比jdk的.net包强何止百倍，
HTTPClient的特点是多个操作可以复用同一个连接，设置连接超时(基于socket)，使用代理验证。具体可以到innovation网站看看对比数据。
如下是灌水程序的简单程序，仅供参考
