6 LWP::Debug - deprecated
7
9 LWP::Debug used to provide tracing facilities, but these are not used
10 by LWP any more. The code in this module is kept around (undocumented)
11 so that 3rd party code that happen to use the old interfaces continue
12 to run.
13
14 One useful feature that LWP::Debug provided (in an imprecise and
15 troublesome way) was network traffic monitoring. The following section
16 provide some hints about recommened replacements.
17
18 Network traffic monitoring
19 The best way to monitor the network traffic that LWP generates is to
20 use an external TCP monitoring program. The Wireshark program
21 (<http://www.wireshark.org/>) is higly recommended for this.
22
23 Another approach it to use a debugging HTTP proxy server and make LWP
24 direct all its traffic via this one. Call "$ua->proxy" to set it up
25 and then just use LWP as before.
26
27 For less precise monitoring needs just setting up a few simple handlers
28 might do. The following example sets up handlers to dump the request
29 and response objects that pass through LWP:
30
31 use LWP::UserAgent;
32 $ua = LWP::UserAgent->new;
33 $ua->default_header('Accept-Encoding' => scalar HTTP::Message::decodable());
34
35 $ua->add_handler("request_send", sub { shift->dump; return });
36 $ua->add_handler("response_done", sub { shift->dump; return });
37
38 $ua->get("http://www.example.com");
