'Response.Charset = 936 '
设置输出编码为简体中文
'Response.Buffer = false '
关闭缓冲区
Dim Fso,ts,IpList,Cfs
'设置Cookies函数
Function SetCookie()
Response.Cookies(
"IsBrow"
) =
"Brow"
Response.Cookies(
"IsBrow"
).Expires = Date+365
End Function
'记录IP地址函数
Function WriteIp(FileName, IpAddress)
Set Fso = Server.CreateObject(
"Scripting.FileSystemObject"
)
Set ts = Fso.OpenTextFile(Server.MapPath(FileName),8,
true
)
ts.WriteLine IpAddress
ts.Close
Set ts = Nothing
Set Fso = Nothing
End Function
'读取IP地址函数
Function ReadIpList(FileName)
Set Fso = Server.CreateObject(
"Scripting.FileSystemObject"
)
If Not Fso.FileExists(Server.MapPath(FileName)) Then
CreateFile(
"Iplist.txt"
)
Exit Function
End If
Set ts = Fso.OpenTextFile(Server.MapPath(FileName))
Iplist = ts.ReadAll
ts.Close
Set ts = Nothing
Set Fso = Nothing
ReadIpList = Iplist
End Function
'创建文件函数
Function CreateFile(FileName)
Set Fso = Server.CreateObject(
"Scripting.FileSystemObject"
)
Set Cfs = Fso.CreateTextFile(Server.MapPath(FileName))
Cfs.Close
Set Cfs = Nothing
Set Fso = Nothing
End Function
'关闭当前IE窗口函数(注:IE6下通过,其他浏览器未测试)
Function CloseWindow()
'Response.Write "<script>window.location='
javascript:window.opener=
null
;window.close();'</script>"
Response.Redirect
"http://www.baidu.com"
End Function
Ip = Request.ServerVariables(
"REMOTE_ADDR"
) '获取浏览者IP地址
Cookie = Request.Cookies(
"IsBrow"
) '获取当前Cookies
'Response.Write Cookie
If Request.ServerVariables(
"HTTP_X_FORWARDED_FOR"
) <>

Then
Response.Write
"本站不允许使用代理访问"
Response.End()
Else
If Cookie =
"Brow"
Then
CloseWindow()
Else
If Instr(ReadIpList(
"Iplist.txt"
),Ip) <> 0 Then
CloseWindow()
Else
WriteIp
"Iplist.txt"
, Ip
End If
SetCookie()
End If
End If
