Stream File to Browser 1

[hedidit]

Hi,

I have a downloads page that lists files located ina folder not in the webroot. I've found some code that streams the file to the browser however I want the user to be prompted to download the file, at the moment it is shown on-screen... zip files show up as loads of random text... not nice!

I've seen lots of posts on these forums but nothing that seems to help... can someone point me in the write direction?

My code is currently:

strFilePath = server.mappath("../../database/" & Session("ORG") & "/") & "/" & Request("FN")
Set objStream = Server.CreateObject("ADODB.Stream")
objStream.Open
objStream.Type = 1
objStream.LoadFromFile strFilePath
fn = Request("FN")
Response.ContentType = "application/octet-stream"
Response.AddHeader "Content-Disposition","attachment;filename=" & fn
Response.BinaryWrite objStream.Read
objStream.Close
Set objStream = Nothing

Cheers

Hi Oonpt,

Thanks as always, unfortunately the site is on a hosted server however that article did help! Now the save file prompt appears but leaves the .zip off the name of the file... any thoughts?

Ok that's wired... the download prompt works fine in IE7 but Firefox downloads the file without the file extension... most of my users will be using IE so I'm happy but how odd!

That is odd. One thing I would warn you about is to not put the Request("FN") variable directly in your filepath without doing some basic checks on it. As it is, it wouldn't be too hard for someone to inject a bad value into it and start downloading files you hadn't intended them to download. With enough playing around they could probably find other files to download, or put enough ..'s to get themselves back to the root of the drive and then find system settings files.
