Sorry1 Forgot to mention that the languages are dynamic in the sense that administrator can add remove languages from the admin panel

Thanks!

I am working on a multilingual site in CakePHP.
Session is being used for storing the language iso2 code and translations are saved in the MySQL tables.

Here the language is changing properly and content depicts it. Now the problem is that how the search engines will know about the language and how can I specify the code in url.

Please guide with your experience.

Thanks!
Take Care!
