新建立一个ASP文件 把 以下代码复制进去

<%
ip=request.ServerVariables("REMOTE_ADDR") '获取来访的IP地址

dim conn
set conn=server.CreateObject("ADODB.connection")
conn.open "Dbq="&server.MapPath("yb/dat/data.mdb")&";Driver={Microsoft Access Driver (*.mdb)}" '建立数据库连接 这里你可以自己改

sql="select * from ip_user where ip地址='"&ip&"'"
set rs=server.CreateObject("ADODB.recordset")
rs.open sql,conn,3,3
if rs.eof then
call ip_fir("thenew")
else
vistime=rs("访问时间")
if DateDiff("h",vistime,now)>=12 then
call ip_fir("theup")
else
call ip_notfir
end if
end if
%>

<%'--------------为了方便写成了过程形式：

Sub Ip_fir(action)'---------------------第一次访问的过程
response.write "12小时内，你是第一次访问本站，这里贴上加流量代码"

if action="theup" then
rs("访问时间")=now()
rs.update
elseif action="thenew" then
sql1="insert into ip_user(ip地址) values ('"&request.ServerVariables("REMOTE_ADDR")&"')"
conn.execute(sql1)
end if
End Sub

Sub ip_notfir()''---------------------12小时内访问过的过程
'---------------------这里改成你期待的处理方式
response.write "你在最近12小时内访问过本站"
End Sub
%>

check_inTime是时间Time(比如8:30:00)
tuihour=hour(rs("check_inTime"))
tuiMinute=Minute(rs("check_inTime"))
chaotime=TimeSerial(tuihour,tuiMinute+10,0)'用这个时间函数返回一个时间！就是往后加10分钟。如果是check_inTime是8:30:00，那么返回时间为：8:40:00 。
if chaotime>time then
Response.Redirect("cuo.asp?id=3")'错误处理页面！可以在这定义说十分钟后才能够注册！
end if
