Apache is the web server. You can use the modrewrite module (? - I think they call it a module, it could be somthing else) to dynamically rewrite urls. This works fine if you just want to be able to create permanent links you can post on other sites but it isn't sufficient if you want the links in your phpnuke site to be static. You would need modify the phpnuke code to crite static urls. I've never worked with phpnuke so I don't know if there are any existing solutions to this. Many projects have a plugin of some description which will handle this. Nice tool by the way nvidura, I'm actually fairly happy working with modrewrite but I've still bookmarked it.
