directive (Apache)">
<IfModule> ... </IfModule>
A sectioning directive for specifying directives that apply if a given module has been compiled into the Apache server. For example:
<IfModule mod_cgi> LoadModule mod_speling libexec/modspelling.so </IfModule>
This directive is executed if Apache is compiled with the mod_cgi module. Note that you can place an exclamation mark in front of the module name to include such directives if a module is not included in the Apache server build.
