    <IfDefine> directive

    +Syntax: <IfDefine [!]parameter-name> ... +</IfDefine>
    +Default: None
    +Context: all
    +Status: Core
    +Compatibility: <IfDefine> is only available in 1.3 and +later.

    + +The <IfDefine test>...</IfDefine> +section is used to mark directives that are conditional. The +directives within an IfDefine section are only +processed if the test is true. If test +is false, everything between the start and end markers +is ignored.

    + +The test in the <IfDefine> section directive +can be one of two forms: + +

    + +

    In the former case, the directives between the start and end markers are +only processed if the parameter named parameter-name is defined. +The second format reverses the test, and only processes the directives if +parameter-name is not defined. + +

    The paramater-name argument is a define as given on the +httpd command line via -Dparameter-, at the +time the server was started. + +

    <IfDefine> sections are nest-able, which can be used to implement +simple multiple-parameter tests. + +Example: + +

    +  $ httpd -DReverseProxy ...
+
+  # httpd.conf
+  <IfDefine ReverseProxy>
+  LoadModule rewrite_module libexec/mod_rewrite.so
+  LoadModule proxy_module   libexec/libproxy.so
+  </IfDefine>
