Question

I’m having trouble figuring out how to do this using Rails, though it is probably cause I don’t know the proper term for it.

I basically want to do this:

def my_action
    sleep 1

    # output something in the request, but keep it open
    print '{"progress":15}'

    sleep 3

    # output something else, keep it open
    print '{"progress":65}'

    sleep 1

    # append some more, and close the request
    print '{"sucess":true}'
end

However I can’t figure out how to do this. I basically want to replicate a slow internet connection.

I need to do this because I am scraping websites, which takes time, where I am ‘sleeping’ above.

Update
I’m reading this using iOS, so I don’t want a websocket server, I think.
