Re: Redirect After Using render('action')

[Tony Thomas]

Thanks Brian,

I thought that might be the case.

 If you really want the form to disappear, use JS to submit the form
 using AJAX and hide/change certain elements of the page.

Redirect After Using render('action')

I dont believe you have any control at all regarding downloads.

Whether Cake spits out a CSV file or redirects to another
controller/action, headers need to be sent to the client, but you
can't send headers for both simultaneously.
