Hidden url for download

Hello everyone ,

I'm coding a download system with ASP. I want to hide the URLs of the files and I want to allow only my members to download the files. I'm using these codes ;

Set FSO = Server.CreateObject("Scripting.FileSystemObject")
Set XFile = FSO.GetFile(Path)
Set TS=FSO.OpenTextFile(XFile)
Response.ContentType="application/unknown"
Response.AddHeader "Content-Disposition", "attachment; filename=" & FileName
Response.BinaryWrite TS.readall & ""
TS.Close
Set TS=Nothing
Set XFile=Nothing
Set FSO=Nothing

' FileName points the system path of the file.

But members download the files in a few seconds but there are some errors. For example 30mb. file downloads as a 1Kb.

I cannot understand reason of this error. What can I do or do you know another secure download system that permit unknown visitors to download files?

and the problems are occured just while downloading the video files (asf,wmw,mpeg). there are no problem while downloadind zip files.

 

I have just found an article that's related about this problem. i couldnt tyr it yet but I'll integrate this solution into my system today and I'll write here the results.
