<IfDefine>

 <IfDefine>  ...  </IfDefine> 

A sectioning directive for specifying directives that apply if a given define is entered on the command line. For example:

 <IfDefine MD5Digest> LoadModule mod_digest libexec/moddigest.so </IfDefine> 

This directive is executed if the Apache server is started using the following command line parameter:

 httpd -DMD5Digest ... 

Note that you can place an exclamation mark in front of the <IfDefine> parameter to include such directives if a definition is not made on the command line.
