Maybe you can get the Content-Disposition with a HEAD request.

$ua->head( $url )

In terms of dumping the headers you can do something like

my @field_names = $response->headers->header_field_names; print "$_ => ", $response->header($_), "\n" for @field_names;

or better yet

$response->headers->scan(sub { my ($key, $value) = @_; print "$key => $value\n"; });

    I can't because the HEAD request (after going through an authorization sequence with time delays) destroys the ability for me to subsequently retrieve the content (one connection, and then the file is "gone").

      You could write the file to a temp file, parse the header, and then rename the file. As an alternative, lwpcook shows how to process a file as it arrives, so maybe you can read the header when the first chunk comes in.

    The second code snippet works perfectly for printing headers. Thank you.
