CodeIgniter is really easy to learn and use, I'm thinking of adding OWASP's ESAPI's functionality as a plugin (if it's worth the effort) in the future, so that more people will come to hear of it, and use it

Meanwhile, have been stuck with a redirect loop problem when I test out my (test) codes with Aptana's built-in Jetty server, for reasons unknown. I guess I'll have to try nginx + PHP-FPM to see whether the source of the problem is really Jetty, or something else...
