You must have missed ngx_echo module, because it's the part that makes this exactly as described in Facebook's BigPipe blog post. I've prepared simple proof-of-concept configuration for nginx: http://labs.frickle.com/misc/nginx_bigpipe.conf http://labs.frickle.com/misc/nginx_bigpipe.conf As you can notice, every "sub-page" is generated individually. Using presented configuration everything is chunked and flushed, so it will be sent to the client right away. Response on the client side looks like this: http://labs.frickle.com/misc/nginx_bigpipe.output http://labs.frickle.com/misc/nginx_bigpipe.output DISCLAIMER: I don't know how Taobao is using released modules internally or if they use them in production already (but I know some portals do).
