[jQuery] File download with jQuery.

[lagos.tout]

Hi,
Anyone know how to force the browser to treat the data returned by the
server in response to $.get( ) as a file, not text or html or xml?
I'm using the correct mime-type and know that the file is being
returned when I use an href on a link, rather than jQuery.  I could
stick with that, but I'd like to know if it's possible to use jQuery
to return data that is treated as a file eg. jpg, pdf etc.
Thanks.
