  1. Probably the most popular approach is to take advantage of a web server that supports URL rewriting. An example of this is an Apache web server configured to use mod_rewrite. You then define rewriting rules that allow graphic file requests and requests for CSS and JavaScript to pass untouched. Otherwise, the request would be funneled through a routing method.

  2. Another potential approach is to simply have your web server virtual host definition point to a specific routing script, which then invokes the routing class, make routing decisions...
