title: Pass post id as a second segment in codeigniter
body: <p>I would like to build the following url for artcles: <a href="http://mysite.com/articles/" rel="nofollow">http://mysite.com/articles/</a><strong>ID</strong>. Where the <strong>ID</strong> is the id of the article, which isn't constant of course. How can the be done using codeigniter? As I know the second segment should be the method name inside the controller...</p>
