ChilliSpot-Lang back to CoovaChilli

[Walter Krivanek, VividVisions]

Hi,

I was wondering if there is a way to add the ChilliSpot-Lang parameter  
back to the CoovaChilli URLs (as query parameter "lang") when it's  
returned in the response of the RADIUS server.

My Login pages are multilingual and it would be great if the pages  
after the login would be shown in the selected language without having  
to use cookies or workarounds.

Here's the workflow I am talking about.
CoovaChilli login page -> Language selection + Login (lang parameter) - 
 > CoovaChilli (converting parameters) -> RADIUS (ChilliSpot-Lang  
parameter) -> CoovaChilli (converting parameters) -> CoovaChilli  
success/failed/... page (lang parameter).

Or is there another way to achieve this?

Thanks!
Walter
