I have a very simple anti-bot spam technique that works extremely well. It requires no javascript, cookies or complicated server weirdness, is fully accessible, has no hidden fields, has negligible overhead and takes just a moment or two to implement. It requires that the user fill out one field with a number, so it's good for anti-bot but will not prevent human spammers. In three years, I have yet to receive any spam on any of the many sites that I have installed this on. Sites that were being bombarded with hundreds of spams daily suddenly became quiet and good emails get though.

A few years ago, I needed a Content Management System (CMS) for my site Voor Beginners and its English counterpart For Beginners. One of the requirements was, that the CMS should use "search engine friendly" URLs. This is fairly easy to accomplish with Linux and Apache; however, another requirement was that the CMS should run on the Windows platform... In this article, I will show how you can "simulate" the effects of .htaccess and mod_rewrite using Microsoft's Internet Information Server (IIS) and classic ASP.
