On that topic: I've got my file upload working properly (it forwards the 
file data to an external site, then saves only if validation works).

But I just started to wonder about something; all my tests have been 
with relatively small files (~40KB) but my end users may be uploading 
some very large files (possibly as large as 500KB, although not for months).

In my python script I use:
    filedata = container.REQUEST.file.read()
then merge this data into a MIME submission for the external web site, 
and on success, save it locally as a "file".

My question is -- aside from memory usage, what problems might there be 
with this approach?

Will the "read()" return all the content, or is there a possibility that 
it will return less than the full file contents?  Any timeout issues 
that I should consider?

I can test with large files, but can't really emulate internet network 
latencies.

Thanks,
Nikko
