Vlogger is a little piece of code borned to handle dealing with large amounts of virtualhost logs. It's bad news that apache can't do this on its own. Vlogger takes piped input from apache, splits it off to separate files based on the first field. It uses a file handle cache so it can't run out of file descriptors. It will also start a new logfile every night at midnight, and maintain a symlink to the most recent file. For security, it can drop privileges and do a chroot to the logs directory.
