hi All,

I'm experimenting with codeigniter but don't really understand how links work.

for example, I have a link like this:

localhost/ci/welcome/cat/7

My base url is localhost/ci, so by clicking on this link I would expect the method "cat" of controller "welcome" to be called.

This method is very simple:

   function cat()
    { 
        echo "just a test.";
    }

Pretty basic - I would expect to see the text on screen, but I just see a 404 -page not found error.

What could be the problem?
