title: Is client_body_buffer_size per-connection?
body: <p>I'm not able to tell from reading <a href="http://nginx.org/en/docs/http/ngx_http_core_module.html#client_body_buffer_size" rel="nofollow noreferrer">the documentation</a> whether <code>client_body_buffer_size</code> means per-connection or per-server (or does it depend on where the directive is set?)</p>
  
  <p>I would like to create a large in-memory buffer (16m) to allow occasional large uploads to be speedy. But I want that to be a <em>shared</em> 16m -- if there are a lot of concurrent uploads then slowing down to disk-speed is fine.</p>
