http streaming

Question

is http streaming possible without using any streaming servers?

Answer 1

Of course. You can output and flush, it gets to client before you end the script, thus it's streaming.

Answer 2

Yes, although libraries have varying level of support. What needs to be used is "http chunking", such that lib does not try to buffer the whole request/response in memory (to computed the content length header) and instead indicate content comes in chunks.
