TMA-APACHE-9.4

Ensure KeepAliveTimeout is Set to a Value of 15 or Less

中レベル 1自動apache

説明

The KeepAliveTimeout directive specifies the number of seconds Apache will wait for a subsequent request before closing a connection that is being kept alive. Every KeepAliveTimeout must be 15 or less (absent means the default 5). Reads the main configuration (APACHE_CONF overrides; default /etc/apache2/apache2.conf, /etc/httpd/conf/httpd.conf or /usr/local/apache2/conf/httpd.conf) and every Include/IncludeOptional file.
