As stated, LWP::UserAgent will be of help here, but make sure to look at the requests_redirectable option if you want to actually see if the URL returns a 300-code. If you leave HEAD and GET as requests_redirectable values, you'll get the results of the codes after the redirection.
use LWP::UserAgent;
my $ua = LWP::UserAgent->new( requests_redirectable => [] );
while(<DATA>) {
chomp;
my $r = $ua->head($_);
print $_,": ",$r->code,"\n";
}
__DATA__
http://www.perlmonks.org/

In this case, the tinyurl URL will return 301. If you leave the request_redirectable option as default, you'll get 200 as status code (coming from perlmonks.org, not tinyurl.com).

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).
