<p>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 <a href="directive-dict.html">Directive Dictionary</a>.</p>
<p>The first column gives the directive name and usage. The second
columns shows the default value of the directive, if a default exists.
If the default is too large to display, the first characters will be
followed by "+".</p>
<p>The third and fourth columns list the contexts where the directive
