httpd.conf VirtualHost settings

Install cronolog. It's cool, fast, and simple. The following VirtualHost block is designed to make efficient log files by removing the junk and the bots. This allows log analysers, like our favorite wusage, to go a hell of a lot faster. You can also analyse the bots separately from the real people.
