( #3333=superdoc: print w/replies, xml ) Need Help??

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?

  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
