You can use the standard ngx_limit_conn and ngx_limit_req modules:
http://nginx.org/en/docs/http/ngx_http_limit_conn_module.html

http://nginx.org/en/docs/http/ngx_http_limit_req_module.html

There're several options, for example,

1. use ngx_srcache + ngx_redis/ngx_redis2 to cache the responses directly:

https://github.com/agentzh/srcache-nginx-module#readme

2. use ngx_proxy to do a reverse proxy to the same nginx server and
use ngx_proxy's cache based on the file system.

Hello agentzh,

For reducing http requests I meant reducing HTTP traffic with sending response on same connection.

For css and js we can combine the content but for images is there some way, Other than spriting, to reduce number of connections?

There are some companies which offers services to optimize websites on the fly and they do reduce the HTTP requests too.

You can use spdy and all requests are going to be done on a single connection.

I think there is limited support of SPDY with Nginx atm. Also it requires TLS so I believe there should be some other options available.

There's an Nginx version of google's mod_pagespeed that has optimizations that reduce the number of image downloads. I've found that this can reduce total response time by 10 to 35%, but it's very website specific. The strange loop hardware device does similar optimizations and appears to get better results, possibly because it varies it's optimizations according to browser type.

I think that the biggest wins are found simply by making all static objects cacheabke with far future expires headers

Google pagespeed module is not an option for me as I want to use varnish and nginx memcache/redis module for some caching purpose. Basically what techniques do strangeloop and google pagespeed use to reduce number of image requests?

Is there any option to combine image requests and response other than spriting?
