About variable in SEO lins language is inside of the path. In old way links (you can choose which one you like in mod options) you have language param in URL. In booth ways language param exists in $_GET on server side (.htaccess cares about it for SEO links). So in your server B you can add plugin which will send error header for requests without language param - just in case if you mess something in your robots.txt file.

Ok, I decided to go with the language= option with robots.txt

User-agent: *


Disallow: /*1$
Disallow: /*2$
Disallow: /*3$
Disallow: /*4$
Disallow: /*5$
Disallow: /*6$
Disallow: /*7$
Disallow: /*8$
Disallow: /*9$
Disallow: /*0$
Disallow: /*.php$

This way I omit the source language.
