Hi, is there any way to send response partially? In PHP you can flush
some data to the client.

You have to return a body object, that responds to each and in there yields for every flush: http://stackoverflow.com/questions/3027435/is-there-a-way-to-flush-html-to-the-wire-in-sinatra/3028149#3028149 (that example is usable without Sinatra)

That example from SO doesn't work for me on ruby 1.9.1p378, sinatra
1.0, rack 1.2.1, and thin 1.2.7 (it just pauses for a while and
returns the whole string). Same behavior on ruby1.8.7p299, sinatra
1.0, rack 1.2.1, and mongrel 1.1.5. Any obvious explanations?

But that's what the example does (the first one). Sleep 0.3 seconds, than flush.

Try this:

	# config.ru
	module Demo
		def self.each
			10.times do |i|
				yield(i.to_s << "\n")
				sleep 1
			end
		end
	end

	run proc { [200, {"Content-Type" => "text/plain"}, Demo]

Make sure to use Thin or something, not sure if it works in Webrick.

Right, I was running the example with the Crawler class that yields
(just had it sleep and return random string as a "search result").
Turns out this works fine with curl or Firefox, but not Chrome
(v5.0.375.125 for Mac). So it is actually an issue with Chrome, not
rack.
