Ensure KeepAlive Is Enabled

中级别 1自动化apache

说明

The KeepAlive directive controls whether Apache will reuse the same TCP connection per client to process subsequent HTTP requests from that client. It is recommended that the KeepAlive directive be set to On. KeepAlive must be On or absent (default On). 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.
