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.
