When you install your opencart in our website, opencart will set current URL as base URL of opencart. For example when you install opencart in http://domain.com, this domain will be set as base URL of opencart and if a visitor enter http://www.domain.com, your website would not have good appearance because of font or script downloading.

This module redirects any other URLs to your opencart base URL. For example if your visitor enter http://opencart.com/index.php?route=cms/company, it will automatically redirect to https://www.opencart.com/index.php?route=cms/company because https://www.opencart.com/ is your opencart base URL. Actually it will force visitors to see your website with www or without it base on your opencart configurations.

This module works with http and https with or without www.

Installation of the module will not affect any files nor it will modify any files.
