I just realized that this is a bit more involved than I at first expected. It would be nice to be able to send the upload request without holding all of postdata in memory, and getPage(), even when I get past the below problem (which can be done by calling something like encode_multipart_formdata() as defined at http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/146306), doesn't seem to allow for that. Fabian Seisen's urllib2_file at http://fabien.seisen.org/python/urllib2_multipart.html, does work without requiring the upload to sit in memory all at once, but it doesn't appear to be asynchronous and it doesn't appear to work with Python 2.4 right now, either. Is there some way I can make this work with HTTPClientFactory? If not, what should I be looking at? In the case of large file uploads, wouldn't it be advisable to send the headers/seperators first, then do a chunk by chunk read of the file and send these chunks one at a time (but in quick succession). To do that, it seems like a write() method is necessary -- is that in the IConsumer interface? Thanks for any guidance you can give me -- as you can tell I'm new to twisted.

How do I correctly set up the payload for a POST file upload? I see that I can add a "method='POST'" and "postdata=something" to getPage(), but it's that 'something' that I'm stuck on. I'm wondering if there isn't a convenience method for putting the right stuff in the HTTP header (Content-Type: multipart...") and in the body (-----seperator, etc).

I haven't been able to find an answer in the mailing list for the above (and google doesn't seem to know, either), but I'm sure there's a really simple way to do it.
