 - BigPipe uses streaming, this means any proxy in between should not buffer the response: the origin needs to stream directly to the end user.
 - Hence the web server and any proxies should not buffer the response, or otherwise the end result is still a single flush, which means worse performance again.
 - BigPipe responses contain the header `Surrogate-Control: no-store, content="BigPipe/1.0"`.

 When using Nginx, the BigPipe module already sends a `X-Accel-Buffering: no` header for BigPipe responses, which disables buffering.
 
 Alternatively, it is possible to [disable proxy buffering explicitly](http://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_buffering).
