The ngx_http_read_client_request_body() function must overwrite request handlers, including r->write_event_handler, or an write event while reading a request body will result in unexpected additional processing. Proper solution would be to fix the form-input module to restore r->write_event_handler to ngx_http_core_run_phases() after the request body has been read (and before the module calls ngx_http_core_run_phases() again). -- Maxim Dounin http://nginx.org/ _______________________________________________ nginx mailing list nginx@nginx.org http://mailman.nginx.org/mailman/listinfo/nginx
