Also have a look at Cache::FileCache:
my $hostname = 'foo.bar.example.com'
use Cache::FileCache;
my $cache = new Cache::FileCache( { 'namespace' => 'HostInfo',
'default_expires_in' => 600 } );
my $cacheKey = $hostname;
my $host_info = $cache->get( $cacheKey );
if ( not defined $host_info )
{
$customer = get_host_info_as_hashref( $hostname );
$cache->set( $cacheKey, $host_info, "10 minutes" );
}
return $host_info;

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).

Want more info? How to link
or How to display code and escape characters
are good places to start.
