I come from a Java background and with any servlets-based technology, it\'s trivial to map a range of URLs (eg /reports/, /secure/.do) to a specified servlet. Now
Can't be done in PHP as such. Note that in Java, it's not the Servlets either that map URLs, but it's the configuration of the servlet container (e.g. Tomcat).
You can achieve similar results for PHP applications by using URL rewriting.
