custom event-mpm settings using pre_main_global.conf

I am using the event mpm and need to change some settings. I have found this is not possible using home >> service configuration >> apache configuration >> global configuration. Why? Well, one scenario is : ServerLimit 20 MaxRequestWorkers 500 If you enter these values in whm will complain about the maxclients value (server limit). So, you can add these in the pre_main_global.conf by using home >> service configuration >> apache configuration >> include editor. In the include I have added : StartServers 5 ServerLimit 20 MaxRequestWorkers 500 MaxConnectionsPerChild 20000 MinSpareThreads 75 MaxSpareThreads 250 ThreadsPerChild 25 ThreadLimit 64 KeepAlive On KeepAliveTimeout 2 MaxKeepAliveRequests 100 most of which are defaults. Here is my question... are these values actually being used!? If you look in the /usr/local/apache/conf/httpd.conf file there are already defaults listed in the file such as : # These can be set in WHM under 'Apache Global Configuration' Timeout 300 TraceEnable Off ServerSignature Off ServerTokens ProductOnly FileETag None StartServers 5 MinSpareServers 5 MaxSpareServers 10 MinSpareServers 5 MaxSpareServers 10 ServerLimit 20 MaxRequestWorkers 250 MaxConnectionsPerChild 20000 KeepAlive On KeepAliveTimeout 2 MaxKeepAliveRequests 100 well, the custom values I set in the include file are included at the top of this file (pre) so since these values come after that include in httpd.conf aren't they being overwritten?
