TMA-APACHE-9.3

Ensure MaxKeepAliveRequests is Set to a Value of 100 or Greater

보통레벨 1자동apache

설명

The MaxKeepAliveRequests directive limits the number of requests allowed per connection when KeepAlive is on. If it is set to 0, unlimited requests will be allowed. Every MaxKeepAliveRequests must be 100 or more (absent means the default 100). 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.
