client to upload big files via https and get progress info

[News123]

Hi,

I'd like to perform huge file uploads via https.
I'd like to make sure,
- that I can obtain upload progress info (sometimes the nw is very slow)
- that (if the file exceeds a certain size) I don't have to
  read the entire file into RAM.

I found Active states recipe 146306, which constructs the whole
multipart message first in RAM and sends it then in one chunk.


I found a server side solutions, that will write out the data file chunk
wise ( http://webpython.codepoint.net/mod_python_publisher_big_file_upload
)



If I just wanted to have progress info, then I could probably
just split line 16 of Active State's recipe ( h.send(body) )
into multiple send, right?

chunksize = 1024
for i in range(0,len(body),chunksize):
    h.send(body[i:i+chunksize])
    show_progressinfo()


But how could I create body step by step?
I wouldn't know the content-length up front?

thanks in advance
