Can I decode gzip when using the mirror function in LWP Useragent?

Can I use something like $response->decoded_content within a LWP UserAgent 'mirror' request? Thank you.

When using mirror() the received data is not added to the response object directly, but instead written directly to the mirror file. This means that decoded_content() will not work. However, you can add a response_header that enables the storage of the received data:

use strict;
use warnings;
use LWP::UserAgent ();

my $ua = LWP::UserAgent->new;

my $fn = 'libwww-perl-6.41.tar.gz';  # Example file..
my $url = 'https://cpan.metacpan.org/authors/id/O/OA/OALDERS/'. $fn;
$ua->add_handler(
    response_header => sub {
        my($response, $ua, $handler) = @_;
        $response->{default_add_content} = 1;
    }
);
my $response = $ua->mirror($url, $fn);
if ( $response->is_success ) {
    if ( $response->header('Content-Type') eq 'application/x-gzip') {
        $response->header('Content-Encoding' => 'gzip');
    }
    my $decoded_content = $response->decoded_content;
    # Do someting with the decoded content here ...
}
