Add `X-Accel-Buffering` to Python SDK
to prevent nginx from buffering stuff
Seems like a good idea. @lllama ?
Still waiting on a review from @lllama...
Hmm. I think there was discussion on Discord that we'd avoid adding specific headers in the SDKs. Do we know if the other SDKs are adding this?
The PHP SDK uses this as a default header, and the Ruby one too, so I think it depends on how common it is to use nginx with Python.
Still on the fence about this one but I don't think it'll do any harm or introduce surprising behaviour, so ok to merge.
Merged, thanks!
