使用ClientSocket控件实现CSDN论坛帖子的自动回复

写此文章的目的不是要鼓励大家恶意灌水，而是要了解Http头信息传输的机制及Cookie的一些知识，讲之前大家先看一下下面我在CSDN所截获的回复帖子的Http包信息内容：

typestate=1&Point=0&TopicName=%B7%A2%CC%F9%B2%E2%CA%D4%A3%AC%CF%D0%C8%CB%CE%F0%BD%F8%A3%A1&Room=1404&Content=rt

//Point：分数0 TopicName：文章标题：发贴测试，闲人勿进！是经过unicode编码的 Content：内容： rt 上面是传递的参数

10.104.9.30(1062)-> //发送方IP及端口

10.104.9.30(80) //接受方IP及端口

POST /Expert/PostNew_SQL.asp HTTP/1.1 //接受页面及HTTP版本

Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, application/vnd.ms-powerpoint, application/vnd.ms-excel, application/msword, application/x-shockwave-flash, */*

Referer: http://expert.csdn.net/Expert/PostNew.asp?room=1404 //提交的地址

Accept-Language: zh-cn //中文语言

Content-Type: application/x-www-form-urlencoded

Accept-Encoding: gzip, deflate //接受压缩格式类型

User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0) //用户环境

Cache-Control: no-cache //没有使用缓存

Cookie: remenber=0; ASPSESSIONIDAAATSBBS=POHKDGIBFHAMPECBCDHIHBCD; room=0; username=dashi888; speaknum=0; speaktime=2003%2D5%2D15+11%3A56%3A34; adminok=True; userid=487815; info1=0; m%5Ftype=1; aszx=0a727a0323230cd62e4cf5326besba01; mid=476831 //COOKIE的内容

注：用户的Cookie是经过32位加密的，我们要先构造自己要发送的Http包信息

截图如下：
