/**

* A servlet filter which adds the {@code lang} parameter to the requested URL.
|
||||
* A the moment the same URL in CCM may point to different language variants of
|
||||
* content. This can be a problem when a cache like mod_cache is used. This
|
||||
* filter redirect the incoming request to an URL with the {@code lang} set to
|
||||
* the default language if the requested URL does not contain the {@code lang}
|
||||
* parameter.
|
||||
*
|
||||
* If the requested URL contains one of the following the filter does nothing:
|
||||
* <ul>
|
||||
* <li>/ccm/admin</li>
|
||||
* <li>/ccm/content-center</li>
|

* <li>/themes</li>
