You may omit "add_header    Cache-Control  public" at all.

The connection_pool_size set initial size of memory pool per connection.
If a connection needs more memory nginx allocates it by chunk of this size.

You may omit and use default values of

connection_pool_size
client_header_buffer_size
large_client_header_buffers
request_pool_size
output_buffers
postpone_output
ignore_invalid_headers
