Rails - Sep 2006 - http post in chunks

This isn''t strictly a rails query. I have created a rails application 
that accepts post data on an action and I''m writing a ruby client that 
sends a file using HTTP::Post. However, the file is quite big and I want 
to display some kind of feedback on the send progress but I can''t work 
out any way to either write in chunks of a small size or to monitor the 
send progress in any other way. Is there a way I can do this?

Well if anyone is interested heres how i solved it:

class VerboseStringIO < StringIO
    def read(len = nil)
       progress = (pos.to_f / length.to_f) * 100
       puts "Progress: #{progress}%"
       super(len)
    end
end

data # string of data to post
tio = VerboseStringIO.new(data)

req = Net::HTTP::Post.new("/controller/action")
req.body_stream = tio
req.content_length = data.length
req.content_type = "text/xml" #or whatever

http = Net::HTTP.new("localhost",3000)
http.read_timeout = 999
response = http.start{|query| query.request req}

This should output:
Progress: 1%
Progress: 2%
Progress: 3%

and so on so you can do whatever and show a progress bar or something.
