9 This module has been deprecated. Please see LWP::ConsoleLogger for
10 your debugging needs.
11
12 LWP::Debug is used to provide tracing facilities, but these are not
13 used by LWP any more. The code in this module is kept around
14 (undocumented) so that 3rd party code that happens to use the old
15 interfaces continue to run.
16
17 One useful feature that LWP::Debug provided (in an imprecise and
18 troublesome way) was network traffic monitoring. The following section
19 provides some hints about recommended replacements.
20
21 Network traffic monitoring
22 The best way to monitor the network traffic that LWP generates is to
23 use an external TCP monitoring program. The WireShark
24 <http://www.wireshark.org/> program is highly recommended for this.
25
26 Another approach it to use a debugging HTTP proxy server and make LWP
27 direct all its traffic via this one. Call "$ua->proxy" to set it up
28 and then just use LWP as before.
29
30 For less precise monitoring needs just setting up a few simple handlers
31 might do. The following example sets up handlers to dump the request
32 and response objects that pass through LWP:
33
34 use LWP::UserAgent;
35 $ua = LWP::UserAgent->new;
36 $ua->default_header('Accept-Encoding' => scalar HTTP::Message::decodable());
37
38 $ua->add_handler("request_send", sub { shift->dump; return });
39 $ua->add_handler("response_done", sub { shift->dump; return });
40
41 $ua->get("http://www.example.com");
