RendahLevel 2Otomatisapache

Deskripsi

The LimitRequestFieldSize limits the number of bytes that will be allowed in an HTTP request header. It is recommended that the LimitRequestFieldSize directive be set to the default value of 8190 or less. LimitRequestFieldSize must be set and every value must be 8190 or less. 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.
