[TYPO3] Storing language prefence in cookie

[serge vleugels]

Hi,

I'm setting up a multilingual site.
I am using sr_language_menu and rlmp_language_detection.

Everything is working fine. My default language, NL, loads perfectly
with nl, or non configured language browser settings

The switching works fine too, but now i would like to store the language
prefs in a cookie. Is there an extension that i havent found, or should
i do this using TS and/or PHP ?

Help would be very much appreciated,
