Question

Answer 1

I know I'm late! But I think I have a solution that's a little cleaner without the use of a hidden iframe and you won't even need an ajax request to do it! Using PHP Headers as noted in the accepted answer in a download.php file

And on the JS end, simply

function download(filename){
    window.location="http://whateveryoursiteis.com/download.php?file="+filename;
}

Works like a charm :O
