How do I realize a UA string block by regular expression in the config files of my Apache webserver?
For example: if I would like to block out all bots from Apache on my debian server, that have the regular expression
/Spider/ in their user-agent.
Those bots should not be able to see any page on my server and they should not appear neither in the accesslogs nor in the errorlogs.
http://global-security.blogspot.de/2009/06/how-to-block-robots-before-they-hit.html supposes to uses
mod_security for that, but isn't there a simple directive for http.conf?
