TMA-APACHE-10.4

Ensure the LimitRequestBody Directive is Set to 102400 or Less but not 0

BajaNivel 2Automatizadaapache

Descripción

The LimitRequestBody directive limits the number of bytes that are allowed in a request body. Size of requests may vary greatly; for example, during a file upload the size of the file must fit within this limit. LimitRequestBody must be set and every value must be 1-102400. 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.
