It also suffices in recent LWP releases to simply say:
my $ua = LWP::UserAgent->new(max_size => 1);
...
for my $url (@list_of_urls_to_check) {
my $res = $ua->head($url);
unless ($res->is_success) {
$res = $ua->get($url);
}
...
}
which effectively does what your callback does in a lot less typing. {grin}

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).
