Question a propos de LWP::Parallel::UserAgent

Bonjour j'ai quelques question a vous posea a propos de

Citation:

en fait je voudrais savoir si il prend en charge la gestion des fichiers robots.txt ?

J'ai un autre prb je cherche un tuto complet et en français sur WWW::Mechanize si vous en avez un contacter moi par MP merci !!!

En fait cette année ont vas étudier ce module de fond en comble en plus il m'intéresse pour mon projet de web spider extracteur d'url comme HTML::LinkExtor mais qui respecte la configuration de LWP.

Pouvez vous m'aider dans mon projet ???

   $ua->timeout(4);
   $ua->env_proxy;
   $ua->requests_redirectable( ['HEAD'] );
   $ua->max_redirect(15000000000);
   $ua->protocols_forbidden( [ 'mailto', 'https', 'gopher', 'ftp', 'socks', 'file' ] );
 
   my $cookie_jar = HTTP::Cookies->new(
     file => 'lwp_cookies.dat',
     autosave => 1,
   );
   $ua->cookie_jar($cookie_jar);
 
  $ua->redirect (1);
  $ua->max_hosts(200);
  $ua->max_req  (200);
