This extension is a little variation of “rlmp_language_detection” written by Robert Lemke. Actually this extension is using 99% of code and documentation from the Robert's one, so please thank and support him instead than me if you feel in need of.

This small extension allows to automatically select a language based on the website domain name (HTTP_HOST).

This is so useful if you have a multilingual website with more than one domain name and you'd like to select the default language depending on the domain the user is using on its browser.

In case that a domain/language match the current page will be reloaded and the appropriate language will be set by using the "L" parameter.

Alternatively the multiple-tree concept for multi-langual websites may be used. In that case the visitor will be redirected to a certain page which acts as an entry page for the preferred language.
