其实我这样做的本意是为了防止盗链！大家帮忙看一下通过代码能够根治盗链！只要不是HTTP_REFERER来源于（google.com google.cn *.google.com *.google.cn baidu.com *.baidu.com）这些网址来源的请求，就通通转发至404
复制代码代码如下:
<%
Dim a, reg
a = Request.ServerVariables(HTTP_REFERER).Item
Set reg = New RegExp
reg.Pattern = ^http://(?:[^.]*/.)?(?:google/.com|google/.cn|baidu/.com)(/|$)
reg.IgnoreCase = True
If Not reg.Test(a) Then
Set reg = Nothing
Response.Status = 404 File Not Found.
Response.End
End If
Set reg = Nothing
' .... 继续
%>
复制代码代码如下:
<%@LANGUAGE=VBSCRIPT CODEPAGE=65001%>
<%Dim OK_URL,URL,HTTP_REFERER
'自定义需要过滤的字串,用 | 分隔
OK_URL= google.com|google.cn|baidu.com'排除信息
OK_URL= split(OK_URL,|) '分割排除信息
URL=404.htm '设定指向页面
HTTP_REFERER=Request.ServerVariables(HTTP_REFERER)'获取来源网址
If HTTP_REFERER<> Then
For Each REFERER In HTTP_REFERER
For i=0 To Ubound(OK_URL)
If Instr(LCase(HTTP_REFERER(REFERER)),OK_URL(i))=0 Then'如果来源网址不是以上排除项的话，那就直接返回所指向的网页！
Response.Redirect(URL):Response.End()
End if
Next
Next
End If%>
