好多朋友做了下载站，但经常被盗链的严重，所以大家可以用这个方法隐藏真实下载地址。让别人无法看到具体的下载地址。复制代码代码如下:
<% FunctIon DownloadFIle(StrFIle)
StrFIlename=StrFIle
Response.Buffer=True
Response.Clear
Set S=Server.CreateObJect(ADODB.Stream)
S.Open
S.Type=1
on Error Resume Next
Set Fso=Server.CreateObJect(ScrIptIng.FIleSystemObJect)
If Not Fso.FIleExists(StrFIleName) Then
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 该文件不存在或者已经删除.
Response.End
End If
Response.RedIrect Request.ServerVarIables(HTTP_REFERER)
Response.End
End If
FileExt=MId(StrFIlename,InStrRev(StrFIleName, .)+1)
Select Case UCase(FIleExt)
Case ASP, ASA, ASPX, ASAX, MDB, PHP, JSP, SHTML, HTML, HTM, TV, DATA
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 该文件不存在或者已经删除.
Response.End
End If
Response.RedIrect Request.ServerVarIables(HTTP_REFERER)
Response.End
End Select
Set F=Fso.GetFIle(StrFIlename)
IntFIlelength=F.SIze
s.LoadFromFIle(StrFIlename)
If Err Then
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 该文件数据不完整或许已损坏.
Response.End
End If
Response.RedIrect Request.ServerVarIables(HTTP_REFERER)
Response.End
End If
Set Upload=Server.CreateObJect(PersIts.Upload)
If Upload Is Nothing Then
