You should use HTTP_HOST variable to get the domain.

See: 
http://art-blog.no-ip.info/cppcms_ref_v0_99/classcppcms_1_1http_1_1request.html#0dc145f6fb337cd352c64a7011bd2142


Then you can extract it with regular expression or something like that.

I would overload cppcms::application::main and set the language there
and the "dispatch" urls as I need.

See for example how wikipp handles this: 
http://cppcms.svn.sourceforge.net/viewvc/cppcms/wikipp/branches/for_cppcms_v100/wiki.cpp?revision=1615&view=markup


Just in your case you should do something like:

    static const booster::regex lang_regex("([a-z]+)\\.tatoeba\\.org");
    void your_app::main(std::string url)
    {
       // set language globally before dispatching
       booster::smatchres;
       std::string domain = request().http_host();
       if(booster::regex_match(domain,res,lang_regex)){
             std::string lang = res[1];
             set_current_language(lang);
       }
       // now execute regular url dispatching.
       cppcms::application::main(url);
    }

P.S.: I also would be glad to hear how does it goes with converting tatoeba.org 
to CppCMS.
