Maybe something along these lines:

require"luarocks.require"
local http = require "socket.http"

print(http.request{
  url = "http://lua-users.org/wiki/FiltersSourcesAndSinks";,
  sink = function(chunk, err)
		if chunk then
			print("got a chunk of length", #chunk)
			-- process chunk and return nil when you don't want to process more 
chunks
		end
		return 1
  end
})
