Correct, rails/unicorn won't know if the client disconnected until nginx breaks the connection to unicorn. > Is a response send back by rails / unicorn fully buffered by nginx?

That's the whole point of using nginx with unicorn. nginx shields unicorn from slow clients. _______________________________________________ Unicorn mailing list - mongrel-unicorn@rubyforge.org http://rubyforge.org/mailman/listinfo/mongrel-unicorn Do not quote signatures (like this one) or top post when replying
