## QoS Settings
<IfModule mod_qos.c>
# handles connections from up to 100000 different IPs
QS_ClientEntries 100000
# will allow only 50 connections per IP
QS_SrvMaxConnPerIP 50
# maximum number of active TCP connections is limited to 256
MaxClients 256
# disables keep-alive when 70% of the TCP connections are occupied:
QS_SrvMaxConnClose 180
# minimum request/response speed (deny slow clients blocking the server, ie. slowloris keeping connections open without requesting anything):
QS_SrvMinDataRate 150 1200
# and limit request header and body (carefull, that limits uploads and post requests too):
# LimitRequestFields 30
# QS_LimitRequestBody 102400
</IfModule>
