说明：  delphi源代码。是木桩同志写的，我只是借花献佛^_^使用了winpcap，所以要先安装之。用途:捕获HTTP的GET和POST消息，用于截获URL的访问以及表单的提交（比如只监听POST消息，可以抓到论坛登陆的帐号和密码）。
(delphi source code. Is written by wood piles, Comrade, I just none ^ _ ^ using winpcap, so first installed. Purposes: to capture HTTP-GET and POST information, visit the URL for the interception, as well as the submission form (for example, listening only POST messages can be caught Forum landing the account number and password).)
