Network traffic monitoring

Another approach it to use a debugging HTTP proxy server and make LWP direct all its traffic via this one. Call "$ua->proxy" to set it up and then just use LWP as before.

For less precise monitoring needs just setting up a few simple handlers might do. The following example sets up handlers to dump the request and response objects that pass through LWP:

  use LWP::UserAgent;
  $ua = LWP::UserAgent->new;
  $ua->default_header('Accept-Encoding' => scalar HTTP::Message::decodable());

  $ua->add_handler("request_send",  sub { shift->dump; return });
  $ua->add_handler("response_done", sub { shift->dump; return });

  $ua->get("http://www.example.com");
