gsiems has asked for the wisdom of the Perl Monks concerning the following question:
I'm trying to create a new route in dancer that will serve as a proxy of sorts to another service. This other service returns various kinds of files of varying size.
For small files, the following snippet works fine:
my $ua = LWP::UserAgent->new(timeout => 180,); $ua->env_proxy; my $rsp = $ua->head($new_route); send_error('Bad Gateway (head)', 502) unless (ref $rsp && $rsp->is_s +uccess); foreach my $key ('Content-Encoding', 'Content-Length', 'Content-Type +', 'Last-Modified') { my $value = $rsp->header($key) || ''; header($key => $value) if ($value); } $rsp = $ua->get($new_route); send_error('Bad Gateway (get)', 502) unless (ref $rsp && $rsp->is_su +ccess); return $rsp->content;
The problem that I'm having is that, for large files, I would like to be able to stream the response. Now LWP::UserAgent allows for grabbing the response in chunks using a callback and Dancer allows sending data in chunks using send_file with a callback but I (as yet) have no clue how to tie the two together in any workable fashion.
Any ideas how to make this work?
