You don't 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 is set.
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.
