I downloaded the source and compiled it. When I read Readme It's little confusing to me. My questions are: AvailableSlotsPercent - does it mean that upto 13 LimitSite can be allocated? LimitSite - does it mean that the site running within the apache itself or the external site trying to access apache server? ClientIpLimit - What's the difference between LimitSiteConnections vs ClientIpLimit? Below is the output from readme: <IfModule mod_slotlimit.c> AvailableSlotsPercent 13 MaxConnectionsPerSite 40 LimitSite www.BadSite.xxx LimitSiteConnections 25 ClientIpLimit 15 ForceVhostName On </IfModule> ------------------------- Directives ------------------------- AvailableSlotsPercent Syntax: AvailableSlotsPercent number Default: 13 Percentage of apache slots available in order to set any restrictions. Setting it to 0 dynamic slot allocation algorithm will be deactivated. MaxConnectionsPerSite Syntax: MaxConnectionsPerSite number Default: No Limit Max connections for each running site LimitSite Syntax: LimitSite site's name Default: Specific site to limit (You can limit differently only one site). Setting this directive you must configure LimitSiteConnections or default value (20) will be used. LimitSiteConnections Syntax: LimitSiteConnections number Default: 20 Max connections for "LimitSite" ClientIpLimit Syntax: ClientIpLimit number Default: No Limit Number of maximum simultaneous connection per IP to the web server. ForceVhostName Syntax: ForceVhostName On|Off Default: Off Force vhost hostname in scoreboard. Vhost hostname do not match site visited under some conditions, for example if you're using mod_vhost_alias. Setting this directive to On, mod_slotlimit will overwrite vhost hostname in apache scoreboard. CustomErrMsg Syntax: CustomErrMsg "My custom error message" Default: "Blocked by mod_slotlimit. More information about this error may be available in the server error log." A custom error message that allows you to replace default error message with one you create --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
