Thank you, Maxim.
I'm looking at ngx_ssl_ocsp_write_handler, and I see that ngx_handle_write_event is called only when the request is fully sent -
it is not called in case of NGX_AGAIN / partial send.
Is this a bug, or am I still missing something?
Also, isn't there a need to call ngx_send repeatedly in a loop, if it somehow returns n < size?
(I see there is such a loop in ngx_linux_sendfile_chain for example)
Thanks again,
Eran
