Chopping file while sending it via ASP response. Binary write

Hi everyone. I use ASP to send files to users to prevent hotlinking and I
Always used following Code

Response. contenttype = "Video/3GPP"
Response. addheader "content-disposition", "attachment; filename =" & file
&";"
Set objstream = server. Createobject ("ADODB. Stream ")
Objstream. Open
Objstream. type = 1
Objstream. loadfromfile "C: \ My. File"
Response. binarywrite objstream. Read
Objstream. Close
Set objstream = nothing

None of the files bigger than 4 MB. But today I have read following
(Couple posts below)

Sub sendfiletoresponse (filepath, filename)

Const clchunksize = 1048576 '1 MB

Dim ostream, I
Response. Buffer = false

Response. contenttype = "application/octet-stream"
Response. addheader "content-disposition ",_
"Attachment; filename =" & filename

Set ostream = server. Createobject ("ADODB. Stream ")
Ostream. type = 1' binary
Ostream. Open
Ostream. loadfromfile filepath

For I = 1 to ostream. Size \ clchunksize
Response. binarywrite ostream. Read (clchunksize)
Next
If (ostream. Size mod clchunksize) <0 then
Response. binarywrite ostream. Read (ostream. Size mod
Clchunksize)
End if
Ostream. Close

End sub

So my question is which one is better and more efficient? In my case only
Mobile phones used to download and I am not sure if copping files cocould
Couse problem.
