the 'old' variant:
caching depends on:
1. Typoscript-conditions
2. fe_usergroups of logged in user
so if you want to cache different values of country you can build in 
conditions on these values. but be aware that other variables which 
might lead to other pagecontent (like 'onemorevariable=xx') are still 
ignored, which can be ok if the value is evaluated just in an uncached
