NAME
LWP::Debug - deprecated
DESCRIPTION
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 program (<http://www.wireshark.org/>) 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");
