Another way is to put common settings on server/http level (and to override
them in location's):

server {
proxy_cache_valid 200 10m;
...

location / {
proxy_pass http://backend.server.org;
}

location /images/ {
proxy_pass http://backend.server.org;
proxy_cache cache;
proxy_cache_valid 200 6h;
}

location /other-cache/ {
proxy_pass http://backend.server.org;
proxy_cache cache;
}
