Ok, that's due to SSL buffering in nginx that isn't configurable.
You can turn it off though by recompiling with this patch.

diff --git a/src/http/ngx_http_request.c b/src/http/ngx_http_request.c

ngx_http_ssl_module);

- if (ngx_ssl_create_connection(&sscf->ssl, c, NGX_SSL_BUFFER)

!= NGX_OK)
{
ngx_http_close_connection(c);
