Hi Maxim,
Thanks for quick response.
I've implemented all upstream callbacks and upstream seems to work fine
now.
But i still have the open question how to avoid sending received data from
upstream to the downstream client.
As I said, I need to process received data first and after that send result
to output.
As i see in the ngx_http_upstream_process_non_buffered_request() buffers
are sent to output if out_bufs are not empty:
if (u->out_bufs || u->busy_bufs) {
rc = ngx_http_output_filter(r, u->out_bufs);
So is it a normal design from nginx point of view to store data in own
buffer (not in u->out_bufs ) to avoid call to ngx_http_output_filter?
I will call it later with my own chain of buffers when all data will be
correctly processed.
Thanks,
Ihor
