<h1>Module Configuration</h1><section class="ls-spacer-small-bottom">Module support is available in Openlitespeed 1.3 and LSWS Enterprise 5.0 and greater.
|
||
|
|
All required modules must be registered under the Server Modules Configuration tab. Module files must be
|
||
|
|
located in the server root/modules folder to be available for registering. On start up, the server
|
||
|
|
loads all registered modules. The server must be restarted after new modules are registered.
|
||
|
|
|
||
|
|
|
||
|
|
Modules can be configured globally under the Server Module configuration tab. The configuration data is
|
||
|
|
then available to the Listener and Virtual Host Module Configurations to inherit or modify.</section>
