An HTTP 500 error is a general error message issued by the server when no more specific 5xx message is appropriate.

Correct. But LWP may also generate 500 errors, as a way to communicate fatal errors to the caller:

#!/usr/bin/perl use 5.010; use strict; use warnings; use LWP::UserAgent; use Data::Dumper; my $ua=LWP::UserAgent->new(); my $resp=$ua->get("http://no.such.server.in.my.lan/no-such-page"); say $resp->status_line; say Dumper $resp;
500 Can't connect to no.such.server.in.my.lan:80 (Bad hostname) $VAR1 = bless( { '_content' => 'Can\'t connect to no.such.server.in.my +.lan:80 (Bad hostname) LWP::Protocol::http::Socket: Bad hostname \'no.such.server.in.my.lan\' + at /usr/lib64/perl5/site_perl/5.12.3/LWP/Protocol/http.pm line 51. ', '_rc' => 500, '_headers' => bless( { 'client-warning' => 'Internal +response', 'client-date' => 'Sat, 17 Nov +2012 19:32:13 GMT', 'content-type' => 'text/plain' }, 'HTTP::Headers' ), '_msg' => 'Can\'t connect to no.such.server.in.my.lan +:80 (Bad hostname)', '_request' => bless( { '_content' => '', '_uri' => bless( do{\(my $o = +'http://no.such.server.in.my.lan/no-such-page')}, 'URI::http' ), '_headers' => bless( { 'user-a +gent' => 'libwww-perl/6.02' }, 'HTTP: +:Headers' ), '_method' => 'GET' }, 'HTTP::Request' ) }, 'HTTP::Response' );
