You could also try lhttpc. Non of the released versions currently support
streaming/partial upload but it's in the main branch of the repository and
I think someone (or several ppl.) are already using it and claiming it
works well. There will be a realese when we've done some additional testing
for the streaming changes, such as the simple load test to see if we're
hurting performance too much with it.

You can find lhttpc either at bitbucket (hg):

or github (git):

You can find examples of how it's done in test/lhttpc_tests.erl. Look for
