I''m not sure if this has been discussed before, but is it possible to
get a file download as a response from Ajax.Request? I know you can
have response txt or xml, but how would I go about requesting a file
download?
Currently I''m requesting the download like this:
window.location =
''http://www.mysite.com/pdf_reports.php?id=1&mnt=05&yr=2005'';
But as you know, this ties up the browser and gives me little control of
the download.
Any thoughts/experiences would greatly be appreciated!

Downloading is a function of the browser itself, not supported in the
XMLHTTP object (you either get text or XML with it)...
The only way I can think to initiate a file download without tying up
your client instance, is to spawn a tiny popup window which initiates
the download. But... that''s a popup. Maybe it can be done with an
iFrame?
But no, definitely not with XMLHTTP (unless I am just WAY wrong)...

Good idea about the iframe! > I''m wondering, what control of the download do you need? It would nice to be able to cancel downloads like you cancel a request: request.transport.abort(); It would also be nice to have multiple downloads asynchronously downloading at one time. Again thanks for the responses and the iframe idea! Ian Tyndall

If, instead you have Content-Type: text/html or Content-Type: text/plain or something else the browser is prepared to render, then it will render the page. -- Raul
> If the server delivers that with the http header > > Content-Type: application/binary > > then you should get the browser behavior you''re looking for.Is that true with the XMLHTTP object? I was under the impression that it''s handling of responses is self contained from the browser (i.e. the browser has no idea when and what types of responses the XMLHTTP object is getting) Maybe the XMLHTTP object passes control back to the browser with that header? Is that what you''re saying? As I said, I COULD be wrong, but I''m gonna have to say no (and sorry but I''m too busy to actually test this). At any rate, even if the browser is notified and takes control away from the XMLHTTP object, that''s not what the OP wants. He wants total behind the scenes control of the download (almost sounds like he wants to build a javascript based download manager). And I''ll stick with my original answer and say it''s not possible.

No, because a) you''re right about XMLHTTP requests not being able to handle this and b) that information is totally wrong, if any, then it should be Content-Disposition: attachment, not Content-Type: application/binary - David Am 16.03.2006 um 15:18 schrieb Ryan Gahl:>> If the server delivers that with the http header >> >> Content-Type: application/binary >> >> then you should get the browser behavior you''re looking for. > > Is that true with the XMLHTTP object?
