LWP::Debug(3)                        User Contributed Perl Documentation                       LWP::Debug(3)



NAME
       LWP::Debug - deprecated

DESCRIPTION
       LWP::Debug 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 happen 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 provide some hints about recommened 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 program (<http://www.wireshark.org/>) is higly 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");
