Sorry, not sure what you are trying to say.

You modify r->limit_rate and r->limit_rate_after from your module
after sending some parts of the response? This is not expected to
work due to the mentioned design limitation of non-buffered
proxying, and generally looks like a bug in your module, it
shouldn't do this.

Further, it is not possible to change upstream buffering after
nginx started sending the response. It's a one-time choice, and
modifications of r->upstream->buffering won't do anything (though
also incorrect, as it's not something expected to be modified by
modules).

Or I understood something incorrectly?
