FileUpload: Content-Type disparity between Firefox & IE

I am creating a file upload utlity very similar to this one: http://authors.aspalliance.com/das/tutorial/test/fileupload2.aspx.

If I upload a simple .txt file the "Content-Type" (FileUpLoad1.PostedFile.ContentType) differs between Firefox and IE:

IE displays "Content type: text/plain"
Firefox displays "Content type: application/save-as"

The problem is that we are going to be storing the files uploaded by the user into a DB and we need to save the content type so that we can stream it properly back to the browser when they go to download the file again from the DB.  With Firefox and IE returning different content types, I can only imagine this will cause problems down the line.

Is this by design? Or will this cause problems later on?

1-This is a major difference between IE and FF and its by design.
2-you don't need to save the content type to enable streaming the files for downloads. you can easily force the file download using
Response.ContentType = "application/x-download"
Response.AddHeader("Content-Disposition", "filename=" & any_filename_includding_its_extension)

see this example here
