Question

Answer 1

You have to use either Content-Length or chunking, but not both.

If you know the length in advance, you can use Content-Length instead of chunking even if you generate the content on the fly and never have it all at once in your buffer.

However, you should not do that if the data is really large because a proxy might not be able to handle it. For large data, chunking is safer.
