Fix Recommendation

Determine the location of the "HTTPD_ROOT" directory and the "httpd.conf" file:

# httpd -V | egrep -i 'httpd_root|server_config_file'
-D HTTPD_ROOT="/etc/httpd"
-D SERVER_CONFIG_FILE="conf/httpd.conf"

Set the "KeepAlive" directive to a value of "on"; add the directive if it does not exist.

Set the "MaxKeepAliveRequests" directive to a value of "100" or greater; add the directive if it does not exist.

Restart Apache: apachectl restart

Determine the location of the "HTTPD_ROOT" directory and the "httpd.conf" file:

# httpd -V | egrep -i 'httpd_root|server_config_file'
-D HTTPD_ROOT="/etc/httpd"
-D SERVER_CONFIG_FILE="conf/httpd.conf"

Search for the directives "KeepAlive" and "MaxKeepAliveRequests" in the "httpd.conf" file:

# cat /<path_to_file>/httpd.conf | grep -i "keepalive"

KeepAlive On
MaxKeepAliveRequests 100

If the value of "KeepAlive" is set to "off" or does not exist, this is a finding.

If the value of "MaxKeepAliveRequests" is set to a value less than "100" or does not exist, this is a finding.
