By default qeury strings are included. You may ignore them using something
like this:

proxy_cache_key $host/$uri";

The default proxy_cache_key approximates

proxy_cache_key $scheme$proxy_host$uri$is_args$args;

Each key takes 128 bytes in shared memory zone. Therefore you need 6.1G zone:

key_zone=NAME:6200m;

Yes, there are such plans.
