High traffic sites can easily get daily logs over 100MB. It can be very beneficial to log only the information we actually use. We will require the minimum logging for decent Awstats reports. We will copy the recommended Apache LogFormat:
"%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\" %V"

For more details on the meaning of these values see: Apache Preferred Awstats Custom Log Formats.

AllowOverride FileInfo Options Limit
</Directory>

This will enable .htaccess in that folder and permit the usage of "order" directive.
