[httpbl] Http Blacklist

[Ruud]

Andreas created a useful extension (which is pretty much as expected) to include an ip blacklist a while ago.

I thought it might be helpful to open a topic for that. Right now I'm testing it with 2.10.2 for which it seems to work. I did change the template filename to html5 and xhtml.

From projecthoneypot.org

The HTTP Blacklist, or "http:BL", is a system that allows website administrators to take advantage of the data generated by Project Honey Pot in order to keep suspicious and malicious web robots off their sites. Project Honey Pot tracks harvesters, comment spammers, and other suspicious visitors to websites. Http:BL makes this data available to any member of Project Honey Pot in an easy and efficient way.

Http:BL provides data back about the IP addresses of visitors to your website. Data is exchanged over the DNS system. You may query your local DNS server and receive a response back that indicates the type of visitor to your site, how threatening that visitor is, and how long it has been since the visitor has last been seen within the Project Honey Pot trap network.

And I also have a question...

Someone asked for a way to test the extension. I changed the code to test if it was working (and it was), but a test mode of sorts might be nice. I'm thinking denying every 5th request as if it was a spammer, every 6th request as if it was a harvester and so on... By denying from the 5th request or so you can still see it allowing as well. Adding output to whatever location in the layout the module is in will also make clear debug/testing is enabled.
