郁闷了2天了．再不能解我真的要郁闷死了．！
我的论坛用了asp防盗链...大家还是先看下这个防盗链的源码吧：
<%
From_url = Cstr(Request.ServerVariables("HTTP_REFERER"))
Serv_url = Cstr(Request.ServerVariables("SERVER_NAME"))
if mid(From_url,8,len(Serv_url)) <> Serv_url then
response.write "非法链接！" '防止盗链
response.end
end if
Function GetFileName(longname)'/folder1/folder2/file.asp=>file.asp
while instr(longname,"/")
longname = right(longname,len(longname)-1)
wend
GetFileName = longname
End Function
Dim Stream
Dim Contents
Dim FileName
Dim TrueFileName
Dim FileExt
Const adTypeBinary = 1
FileName = Request.QueryString("FileName")
if FileName = "" Then
Response.Write "无效文件名！"
Response.End
End if
FileExt = Mid(FileName, InStrRev(FileName, ".") + 1)
Select Case UCase(FileExt)
Case "ASP", "ASA", "ASPX", "ASAX", "MDB"
Response.Write "非法操作！"
Response.End
End Select
Response.Clear
if lcase(right(FileName,3))="gif" or lcase(right(FileName,3))="jpg" or lcase(right(FileName,3))="png" then
Response.ContentType = "image/*" '对图像文件不出现下载对话框
else
Response.ContentType = "application/ms-download"
end if
Response.AddHeader "content-disposition", "attachment; filename=" & GetFileName(Request.QueryString("FileName"))
Set Stream = server.CreateObject("ADODB.Stream")
Stream.Type = adTypeBinary
Stream.Open
if lcase(right(FileName,2))="rm" then '设置rm类型文件目录
TrueFileName = "/kang/"&FileName
end if
if lcase(right(FileName,3))="wmv" then '设置wmv类型文件目录
TrueFileName = "/kangkang/"&FileName
end if
if lcase(right(FileName,3))="gif" or lcase(right(FileName,3))="jpg" or lcase(right(FileName,3))="png" then
TrueFileName = "/kang/2005-9/"&FileName '设置图像文件目录
end if
Stream.LoadFromFile Server.MapPath(TrueFileName)
While Not Stream.EOS
Response.BinaryWrite Stream.Read(1024 * 64)
Wend
Stream.Close
Set Stream = Nothing
Response.Flush
Response.End
%>
大家注意，现在我用这个防盗链在论坛里插入一张图片：
www.51755.com/ceshi.asp?filename=1.jpg 这张图片可以正常显示在论坛里
下面再插入个影音文件在线播放的：
[rm]www.51755.com/ceshi.asp?filename=intro.rm[/rm]问题出现了．这个影音文件不能播放．播放器提示需要附加组件才能播放文件．然后就是找不到组件，不能播放此文件！但我用这个地址提供下载一切正常，我实在郁闷，为什么可以下载，而不能在线播放呢，问题出在那里，小弟拜跪求解！
