You _can_ repeat acces_log in every location. If nginx complains -
you did something wrong (tried to repeat log_format?).

Something like this will do logging into normal.log for all
requests, and additionally to cache.log in a locations where it's
needed:

log_format cache "...";

access_log /path/to/normal.log combined;

server {
...

location / {
proxy_pass http://uncached;
}

location /foo {
proxy_pass http://foo;
proxy_cache one;
access_log /path/to/normal.log combined;
access_log /path/to/cache.log cache;
}

location /bar {
proxy_pass http://bar;
proxy_cache one;
access_log /path/to/normal.log combined;
access_log /path/to/cache.log cache;
}
}
