Hi, Another error I met recently. It occurred when both padding and continuation are enabled.
A normal HEADERS frame was divided as follows: HEADERS ===> HEADERS(PADDED_FLAG) + CONTINUATION + CONTINUATION After sending these frames, I got an error. In the debug log file, I found "client sent inappropriate frame while CONTINUATION was expected while processing HTTP/2 connection". Then I read the source code (v 1.9.9), and located the function "ngx_http_v2_handle_continuation" (ngx_http_v2.c, line 1749). It seems NGINX does not skip the "padding part", but tries to read "type" field in the next CONTINUATION frame directly. However, when testing padding and continuation frame separately, NGINX can handle both cases well. I don't know whether I did something wrong or this is a bug in NGINX. I also sent the same frames to other servers (nghttp, h2o, GWS), and got the responses successfully. Thanks! Shengtuo Hu
