This a lot easier than you think ...
my $ua = LWP::UserAgent->new;
my $request = HTTP::Request->new('GET' => $url);
my $response = $ua->request($request)
if ($response->is_error) {
...
} else {
...
}
Alternatively, you could employ the is_success method for testing for successful retrieval of the passed URL. Furthermore, the actual numeric response code received can be returned with the code method. For further details on HTTP::Response methods, see the HTTP::Response man page.
perl -e 'print+unpack("N",pack("B32","00000000000000000000000111000011")),"\n"'

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).
