Could you please give more information. Do you want a perl
client side solution (for example a script that you can
run to change the word document to have different urls). Or do you
want a
server side solution so that when the link is selected
a proper page is displayed? You really need to further refine what
and where you want to happen.
If it's server side. Just create the proper files with the meta
tag stuff.
<html>
<body>
<meta http-equiv="refresh"
content="2;url=http://www.your.com/construction.html">
Redirecting to construction page!
</body>
</html>
Of course you could also do some funky things like create a custom error handler and hook that into apache.
Now if what you want is a client side solution where you
actually need to modify the word doc - then I can't help you except to say you have a mixed up idea of where redirection happens. The only thing that happens in the word doc is an HTTP request is made - its up to the server to redirect. If you want to handle this on the client, you need to modify the doc and replace the bad URLs with good ones.
