I see that DownloadLink can be used to stream a File.
What I want to do is use DownLoadLink to redirect to an external URL
that should be streamed (i.e. File Save box should pop up).
I can't use ExternalLink as the external URL's location is not pre determined,
also the external URL's location lookup is a costly so I don't want to do it
unless
the User clicks on a link.
So in my case I do some thing like
class DownloadUrlLink {
onClick() {
URL externalUrl = getExternalURL(); //this is a costly operation, so I don't
want to do it unless user clicks the Download link.
getRequestCycle().setRequestTarget(new RedirectRequestTarget(url.toString()));
}
}
The URL points to a rather large gzipped XML file about 11MB in size.
But instead of popping up a File Save dialog, the browser starts to display the
XML file.
and CPU usage jumps up to 100%, on account of the file being this large.
Is there a way to force the browser to pop up a FileSave dialog when using
RedirectRequestTarget
