[support] how to handle internal links

[Ray Zimmerman]

I'm building a site that is currently in a sub-directory of my web  
server document root, but when it is finally deployed it will be in  
the document root. So currently node 99 is at, e.g.

    http://example.com/dev/node/99

... but when I deploy the site it will be at ...

    http://example.com/node/99

My question is, what is the best way to link to node/99 from the body  
of another node, and have it work on my dev server as well as the  
production server? Is there an input filter that converts a URL that  
is relative to drupal's root into an absolute URL?
