# LWP::Debug - phpMan

## NAME
    [LWP::Debug] - deprecated

## DESCRIPTION
    This module has been deprecated. Please see [LWP::ConsoleLogger] for your
    debugging needs.

    [LWP::Debug] is used to provide tracing facilities, but these are not used
    by LWP any more. The code in this module is kept around (undocumented)
    so that 3rd party code that happens to use the old interfaces continue
    to run.

    One useful feature that [LWP::Debug] provided (in an imprecise and
    troublesome way) was network traffic monitoring. The following section
    provides some hints about recommended replacements.

  Network traffic monitoring
    The best way to monitor the network traffic that LWP generates is to use
    an external TCP monitoring program. The WireShark
    <<http://www.wireshark.org/>> program is highly recommended for this.

    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>");
