我们监控到的HTTP数据包有两个属性很重要：
POST ：后面的东西，就是说这个请求处理的页面（URL）
Cokie：保持HTTP请求连续的标志，
还有一个也很重要：Referer，因为好多网站判断这个标志是否来自什么地方请求防止恶意注册，呵呵，知道该怎么做了吗？模拟你的请求吧！准备写个自动注册的东西，开始工作。寻找目标http://foxconnbbs.com/index.asp，呵呵，富士康的，我喜欢！随便找个帖子：http://foxconnbbs.com/dispbbs.asp?boardID=3&ID=3749&page=1注意URL参数的写法，这个和你自动生成所有的回帖有关，我就不在写这个Demo！只是真对这个帖子用Dot.Net实现外部提交！打开ieHTTPHeaders，分析下提交的数据格式:
呵呵，直到处理提交的URL: savepost.asp?action=sre&method=fastreply&BoardID=3，呵呵，别忘记前面加http://foxconnbbs.com/。为什么？晕到！Cookie也知道了吧！呵呵，提交的数据就是这一部分了。结下来就是如何模拟这个请求了，要想模拟这个请求，必须得出cookie的值，呵呵，如何得到这个Cookie哪？还得模拟登陆获得！看下登陆界面：
点击登录后注意提交数据，
呵呵，自己分析吧！
Ok!开始干活，自动登录获得Cookie的方法如下：
