Simply amazing datahell! Genius.
If I wanted to do this for two languages, I can see it works by just adding the code twice; once for each language.
But is there a syntax to say IF OR?, e.g. if currentLang is fr or es? I tried just adding both with a comma separator but it didn't work haha.

I guess you also re-direct AJAX calls, which you should n't. AJAX calls are towards inner.php file. Check this out.

PS. I would do it differently. Remove the re-direction from htaccess and add a re-direction in your template's index.php file, it is much easier to handle. I will write you the code in 5 minutes.

Hi datahell,
there might not be any solution to this, but wondering if you have any suggestions: on a website where there is no FR-lang content except Directory component content; I want to redirect all /fr/ urls except fr/directory-content/

This .htaccess instruction (Apache) works great:

RewriteCond %{REQUEST_URI} !^/fr/directory-content/
RewriteRule ^fr/(.*)$ /$1 [L,R=301]

So, example.org/fr/about/ redirects to example.org/about/
but example.org/fr/directory-content/ does not redirect.

However, even though the FR-lang pages in the directory component are not redirecting, they are not loading either. There is an error message.
The landing page works great. I can see all the directory content in French.
But if I click into any listing, this error message appears: Could not load listing! Invalid response (1) from Directory server.

My only solution has been to un-enable FR in the directory plugin, i.e. remove it from the "Enabled languages".
So at least we can see the FR-listing titles on the landing page, but now if we click into one, it's in the default language (English) even though we are on the the FR-lang page.

Do you think there is any way to enable the language and not have the error message?

Great! Do you know where the name 'Bubbles' can be edited, where the component name it appears in the cPanel sidebar menu?
I can't find where to change that in the language files.

Ah, I see it's under 'Route' in the component's Basic Settings
