CacheHelper saving the same cached files under different names - cakephp

Question

I'm having troubles with the CakePHP's (2.3) CacheHelper.
This is realy a powerful tool, but it's not so suitable for what I'm doing.
I have a internationalised website and the language is set either by the user's preferences or by "forcing" it with an URL argument (lang:xx).
So, the cached page "controller/action/yy" can be the same page as "controller/action/yy/lang:xx". And worst, "controller/action/yy" can be cached in english, french or whatever.
Is there a way to change the name (the prefix is clearly not a solution here) of the cached file (so that "controller/action/yy" will always be cached as "controller/action/yy/lang:xx" by adding the user's preferences language) ?
Thanks in advance !

You can in your beforeRender change the prefix of the file:
Configure::write('Cache.viewPrefix', 'YOURPREFIX');
And you can get your prefix from params or session (depends of your app).
I didn't get why prefix is not useful. You will have one file for each language for each page. Something like "eng_my_action" file.
If you want to save only 1 file and translate it with the user language makes non sense. Because view already do that (only a parser of the data).

Well,
I will sample the awnser to you understand:
public function beforeRender(){
$lang = isset($this->params["named"]["lang"]) ? $this->params["named"]["lang"] : "eng"; // verify if is the default language(eng) or is in params
if($this->Auth->user("lang")){
$lang = $this->Auth->user("lang"); // This is a example how to take the default language from a user. You need to change it to your app.
}
Configure::write('Cache.viewPrefix', $lang);
}
