php - Zend Framework 2 Module to Sub domain mapping

I am working on a project with two modules as Web and Cms. I want to use sub domains with these modules.

mydomain.com -> Web Module

cms.mydomain.com -> Cms Module

I used below module.config.php files in each modules

Web Module -> module.config.php

<?php

     'controllers' => array(
         'invokables' => array(

This doesn't work as expected. Web modulemydomain.com shows it's layout but view content not loading. CMS also showing the web module when I trycms.mydomain.com. Could you please guide me where the issue is.
