Multi domain setup

If you want to share users Cookie Consent between multiple domains (like en.example.com / cz.example.com or exmaple.com / example.cz) you have two options:

Subdomains

If you need to share cookie consent between subdomains (like en.example.com, cz.example.com, demo.example.com etc.), you just need to specify Cookie domain (and Cookie path, if necessary) in advanced settings.

In such case, you just need to specify for which domain the cookie should be valid. So for example value of .example.com will cover all subdomains of example.com domain, including for example www.example.com, en.example.com, cs.example.com or demo.example.com.

This doesn't need to be done, if you set this already in global Joomla configuration.

Multiple domains

If you use multiple domains (like example.com, example.cz, otherexample.com etc.) you need to specify all of these domains in Multiple domains field in advanced settings.

Setup

In both cases on all involved domains has to be of course installed n3t Cookie Consent, with completely same setup. If you use some multi domain plugin (like n3t Language domains for example), you don't need to care, as all domains are running on same Joomla instance (database), so you have installed just one instance of plugin.

If you share Cookie Consent between multiple Joomla instances, you can use Export / Import function to share the settings.
