复制代码代码如下: <% Dim CC_Info(4),strInfo,strTemp If Session("CC_Info") = "" Then CC_Info(0) = "cclog.txt" '日志文件名 CC_Info(1) = Request.ServerVariables("HTTP_X_FORWARDED_FOR") CC_Info(2) = Request.ServerVariables("REMOTE_ADDR") CC_Info(3) = 10 'N秒内禁止刷新当前页面 CC_Info(4) = "badip.txt" 'IP黑名单文件名 Session("CC_Info") = CC_Info(0) &"|"& CC_Info(1) &"|"& CC_Info(2) &"|"& CC_Info(3) &"|"& CC_Info(4) Else strInfo = Split(Session("CC_Info"),"|") CC_Info(0) = strInfo(0) CC_Info(1) = strInfo(1) CC_Info(2) = strInfo(2) CC_Info(3) = strInfo(3) CC_Info(4) = strInfo(4) End If Const chkRefresh = 1 '0关闭防刷新 Const chkProxy = 1 '0关闭代理验证 Const chkBadIP = 1 '0关闭IP黑名单 If Session("BadIP") = "" Then strInfo = ReadFile(CC_Info(4)) If strInfo = "" Then strInfo = "chinavb.net" Session("BadIP") = strInfo Else strInfo = Session("BadIP") End If '/*第一层判断，N秒内禁止刷新*/ If chkRefresh = 1 Then If Session("RefreshTime")="" Then Session("RefreshTime")=Now() Else If DateDiff("s", Session("RefreshTime"), Now()) < CInt(CC_Info(3)) Then Response.Write("系统繁忙，请稍候再试！错误代码001") Response.End() Else Session("RefreshTime")=Now() End If End If End If '/*第二层判断，代理禁止查看*/ If chkProxy = 1 Then If CC_Info(1) <> "" Then If InStr(strInfo,CC_Info(1)) = 0 Then strTemp = CC_Info(1) & vbCrLf If InStr(strInfo,CC_Info(2)) = 0 Then strTemp = strTemp & "[" & CC_Info(2) & "]" & vbCrLf End If SaveLog CC_Info(4),strTemp strInfo = strInfo & strTemp Session("BadIP") = strInfo End If '记录CC攻击日志 SaveLog CC_Info(0),CC_Info(1) & "["& CC_Info(2) & "]" & Now() &vbCrLf Response.Write("系统繁忙，请稍候再试！错误代码002") Response.End() End If End If '/*第三层判断，IP黑名单禁止查看*/ If chkBadIP = 1 Then If InStr(strInfo,CC_Info(2))>0 Then Response.Write("系统繁忙，请稍候再试！错误代码003") Response.End() End If End If 'ForReading=1,ForWriting=2,ForAppending=8 Function SaveLog(filename, filecontent) On Error Resume Next Dim fso, thisfile filename = Server.MapPath(filename) Set fso = CreateObject("Scripting.FileSystemObject") If Err <> 0 Then Response.Write("写入文件"&filename&"失败，可能您的系统不支持FSO！") Response.End() End If Set thisfile = fso.OpenTextFile(filename, 8, True) thisfile.write (filecontent) thisfile.Close Set fso = Nothing End Function Function ReadFile(filename) On Error Resume Next Dim fso, thisfile Set fso = CreateObject("Scripting.FileSystemObject") If Err <> 0 Then Response.Write("读取文件"&filename&"失败，可能您的系统不支持FSO！") Response.End() End If Set thisfile = fso.OpenTextFile(Server.MapPath(filename), 1, True) ReadFile = thisfile.ReadAll thisfile.Close Set thisfile = Nothing Set fso = Nothing End Function %>

其实这类问题就是因为缓存问题，大家可以参考下面的方法解决:有些ASP页面第一次打开的时候会出现Response 对象错误 'ASP 0156 : 80004005' HTTP 头错误，但刷新后又正常了，解决方法如下复制代码代码如下: Respo>>>详细阅读
