HTTP::SimpleLinkChecker - Check the HTTP response code for a link
my $code = HTTP::SimpleLinkChecker::check_link($url);
unless( defined $code )
print "Error: $HTTP::SimpleLinkChecker::ERROR\n";
You dont have to know anything about objected-oriented Perl, LWP, or
the HTTP module to be able to check your links. This module is
designed for the casual user. It has one function, check_link, that
returns the HTTP response code that it receives when it tries to fetch
the web address passed to it. The undef value is returned for any
non-HTTP failure and the $HTTP::SimpleLinkChecker::ERROR variable
The HEAD method is tried first, although if anything other than a good
status code (those less than 400) is received, another request is made
with the GET method. Note, however, that even with the best code, no
module can control how servers decide to respond to a check, or
control any of the myriad things that can go wrong with the network
between you and the remote server. Some may filter requests based on
origin IP address, user-agent type, or any other arbitrary factor.
Some servers may not respond correctly at all. Furthermore, some
servers might be temporarily down or overloaded. I recommend that you
recheck broken links a couple times over a long period (like a day
or two) before you decide they are really broken.
If you are behind a firewall or proxy, this module picks up those
settings through LWP::UserAgents env_proxy() method. See
LWP::UserAgent for more details.
check_link( URL )
Returns the HTTP response code for URL.
Returns a reference to the LWP::UserAgent object. You
can affect it directly. See LWP::UserAgent.
my $ua = HTTP::SimpleLinkChecker::user_agent();
$ua->from( email@example.com );
$ua->agent( Mozilla 19.2 );

members of the project can shepherd this module appropriately.
