[KLUG Members] Blocking By User Agent

[Ron Sweeney]

I used the following article while trying to hookup my .htaccess for Ruby on
Rails to do just that.  Instead of using a Rewrite (which is extremely
flexible, but a little complicated) it involves setting an environment
variable, and then setting up a deny based on that variable:

 # Known mail harvesters
SetEnvIf User-Agent EmailCollector BAD_BOT
SetEnvIf User-Agent CherryPicker BAD_BOT

# Code Red and Nimda
SetEnvIf Request_URI ^/default.ida BAD_BOT=worm
SetEnvIf Request_URI root.exe BAD_BOT=worm

# Referrer spam
SetEnvIfNoCase Referer ^http://(www.)?xopy.com BAD_BOT=spammer
SetEnvIfNoCase Referer ^http://(www.)?aizzo.com BAD_BOT=spammer

# Bad bot, no cookie!
Order Allow,Deny
Allow from all
Deny from env=BAD_BOT
