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' );

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
