-          The <command>IfDefine</command> tags surround configuration directives that are applied if the "test" stated in the <command>IfDefine</command> tag is true. The directives are ignored if the test is false.

-      <para>
-        The test in the <command>IfDefine</command> tags is a parameter name (for example, <command>HAVE_PERL</command>). If the parameter is defined, meaning that it is provided as an argument to the server's start-up command, then the test is true. In this case, when the Web server is started, the test is true and the directives contained in the <command>IfDefine</command> tags are applied.
