Downloading a file in the server with javascript

[stevember]

I have an ASP.NET web application. At some step I create a text file and store it in a folder on the server. I do this on the server code. But then just after getting done with creating the file I want to download that file to client computer. Is this even possible? I know about John Culviner's jquery filedownload plugin. But after reviewing it I understood that the file to download must be in the same directory where the web site itself resides - like www.mywebsite.com/downloads/text1.txt. But I would like to put the created files into some other directory. I feel that ftp will come into play here but don't exactly know how. Could you please guide me a little.
