LoadModule

LoadModule module filename

mod_so

module is the name of the external variable of type module in the file and is listed as the Module Identifier in the module documentation. For example (Unix, and for Windows as of Apache 1.3.15):

For example (Windows prior to Apache 1.3.15, and some third party modules):

LoadModule foo_module modules/ApacheModuleFoo.dll
