( #3333=superdoc: print w/replies, xml ) Need Help??
Thank you very much! Anyway, I think there is something I am getting wrong... When I use the cgi::application's header_prop (in the download_file subroutine) what I'm actually doing is a redirection to the download window, is it right? Cause I tried to make a redirection after the execution of the subroutine, but in this case the download doesn't start. If I put a sleep command after the subroutine, the script executes before the sleep command and then launches the download. So...I don't really understand this behaviour. I tried :
$self->download_zip(); sleep 5; my $filename = "temporaneo/" . $self->session->param("nom_projet") + . ".zip"; unlink $filename;
and
$self->generate_zip(); $self->download_zip(); return $self->redirect("http://delete.cgi");
What I was trying to do was following your advice: put the zip file in another directory and, if succeed, redirect to another run mode that erases the file, otherwise stay on the page and relaunch the download.

    [ambrus]: you just need an io watcher, created by &AnyEvent::Impl:: Whatever::io(...)
    [Corion]: So after talking it through with you even while I'm still not entirely clear on where AE ends and my implementation begins, I think I understand that I only need to implement some smaller parts for each functionality I want to support.
    [Corion]: Yeah... and you might even be able to mix and match additional functionality if you have additional async suppliers, like from a separate thread
    [ambrus]: You hvae to be careful with the timer, because apparently Prima::Timer insists on being periodic, wheras AnyEvent::Impl:: Whatever::timer should give a one-shot timer watcher
    [ambrus]: I think the minimal implementation here is just a timer and io function, plus pushing to the @REGISTRY.
