参考答案:Dim Query_Badword,Form_Badword,Err_Message,Err_Web,form_name
'------定义部份 头----------------------------------------------------------------------
Err_Message = 1 '处理方式：1=提示信息,2=转向页面,3=先提示再转向
Err_Web = "Err.Asp" '出错时转向的页面
Query_Badword="'‖and‖select‖update‖chr‖delete‖%20from‖;‖insert‖mid‖master.‖set‖chr(37)‖="
'在这部份定义get非法参数,使用"‖"号间隔
Form_Badword="'‖%‖&‖*‖#‖@‖=‖select‖and‖set‖delete" '在这部份定义post非法参数,使用"‖"号间隔
'------定义部份 尾-----------------------------------------------------------------------
