ASP实现防止网站被采集代码

ASP实现防止网站被采集代码如下:

<％ 
Dim AppealNum,AppealCount 
AppealNum=10 '同一IP60秒内请求限制10次 
AppealCount=Request.Cookies("AppealCount") 
If AppealCount="" Then 
Response.Cookies("AppealCount")=1 
AppealCount=1 
Response.Cookies("AppealCount").Expires=DateAdd("s",60,Now()) 
Else 
Response.Cookies("AppealCount")=AppealCount+1 
Response.Cookies("AppealCount").Expires=DateAdd("s",60,Now()) 
End If 
If Int(AppealCount)>Int(AppealNum) Then 
Response.Write "抓取很累，歇一会儿吧！" 
Response.end 
End If
