How to differentiate example.com/my and example.com/en?

General questions
1

We are using drupal’s language to create different editions, i.e.

example.com/my
example.com/en

both are on the same website but I need to treat the two as separate sites, how can I do it?

2

Add the domain twice to piwik and then use the different tracking codes to differentiate them.

3

We are using the piwik module which does not allow more than 1 tracking
code per site.

Guess different tracking codes for different languages may not work in this
scenario

thank you anyway. Lets see whether the piwik module on drupal is
customizable for the above
