如何提高在ASP一個「文件下載」和防止熱鏈

Question

我有這樣的代碼在PHP中：

header("Content-Type: application/vnd.ms-excel"); 
header("Content-Type: application/download"); 
header("Content-Length: ".filesize($path.$filename)); 
header("Content-disposition: attachment; filename=" . urlencode($filename)); 
readfile($path.$filename); 

在第一次，我在ASP中使用：

<% 
    Response.AddHeader "content-disposition","attachment; filename=download.xls" 
%>

Set ObjStr = Server.CreateObject("ADODB.Stream")

ObjStr.Open 

ObjStr.LoadFromFile "D:\Folder\edital.pdf" 

varBuffer = ObjStr.Read 

Response.buffer = true 

Response.AddHeader "content-disposition","attachment;" 
Response.ContentType = "application/pdf" 
Response.CacheControl = "public" 

Response.BinaryWrite varBuffer
