Welcome to the simples3 wiki!

Quick note here: there is no direct streaming support for simples3. It’s sad, I did try very hard to get there (because it would be so awesome), but no. urllib/urllib2 ain’t no cuttin’ it. They’re designed in a way which makes it impossible, lest you start hacking around their internals and send the data over the wire yourself (at which point you just lost the point in using a library.)
