The directive quick reference shows the usage, default, status, and context of each Apache configuration directive. For more information about each of these, see the Directive Dictionary.
The first column gives the directive name and usage. The second column shows the default value of the directive, if a default exists. If the default is too large to display, it will be truncated and followed by "+".
The third and fourth columns list the contexts where the directive is allowed and the status of the directive according to the legend tables below.
