you can't get a "save as" dialog if the contents of the file are retrieved
via ajax (browsers don't work like that). Open a new window pointing to the
download url (it will soon close as there's no content to show, and the
"save as" dialog will pop up).
PS: you'd really want to use another system than the simple concatenation
to build the url... if "content" in your case contains csv data, you will
never be able to reach that url (because it won't be a valid url).
As last resort, at least urlencode the content. But you'll then face the
limitation of url size, and that's why usually those kind of things are
made with intermediate temp files or (slightly more complicated in a new
window) POST requests :P
