I've just made the 0.5 release of my Apache2 module mod_ifier.

This module allows you to filter incoming HTTP requests which are sent to your Apache 2 webserver - blocking Referer Spam, dropping webspiders, and preventing many common security attacks.

It is now at a point where it completely replaces the use of mod_security for me. Robust, fast, and reasonably featureful!

Comments or suggestions welcome. The new release should hit unstable sometime tomorrow.

I'm actually fairly pleased with the design now, and there are just a couple of updates to make in the areas of logging and new rule-types.

Once the core is nice and stable the real value of the module comes in the rule-sets. Already I've built up a nice collection of things I want to block from accessing this site, and I look forward to seeing what other people come up with.
