It seems like you could achieve what you want by using fork:

    post '/info' => sub {
        my $tmp_href = params;
        # ...
        my $pid = fork;
        if ($pid) {
            return $tmp_href;
        } else {
             # DO SOME POST RETURN STUFF HERE
        }
    };

Your tmp_href response would return immediately, but a child process would
keep running in the background doing your POST RETURN STUFF.

Though the proper way to do something like this is with some sort of a
messaging/worker system. See for example:

https://metacpan.org/pod/POE::Component::MessageQueue
