How to set mime types

[colinod]

I have a web page with various mp3 files on it adn am trying to pigure out how to set a mime type for downloads because i have some people who are downloading the files and they are being given a .mpeg file extension.

The page is written in asp and have tried

<% Response.ContentType = "audio/mpeg" %>

but this just makes the page open and try and load quicktime.

Not even sure if this would be the right area of the website

thanks

The way I have always done the delivery of file types of this nature is to use an ADO Stream.

Here's the idea:

1. Determine which file the user wants to download.
2. Ensure the file exists.
3. Get the absolute filepath of the file.

4. Add a Content-Disposition header to the response :

Response.AddHeader "Content-Disposition", "attachment; filename=" & YOUR-FILE-NAME

5. Add the file's size as a Content-Length header to the response :

Response.AddHeader "Content-Length", YOUR-FILES-FILESIZE

6. Now open an ADO Stream in binary mode:

Set objStream = Server.CreateObject("ADODB.Stream")  
objStream.Open  
objStream.Type = 1  
Response.CharSet = "UTF-8"

7. Send the binary stream to the user's browser:

Response.BinaryWrite(objStream.Read)

8. Close down used objects

objStream.Close  
Set objStream = Nothing

NOTE: It is important to note that you shouldn't include anything else in the output when the file is found and set as binary data to the user; as this would result in a corrupt download.
