In the same case, Mobile phone ok

Is it a Keep-Alive problem?

[davidmoreno]

I'm no sure that it could be. If it uses the sendfile syscall it may get confused.. not sure. Can you try to disable sendfile (envvar `ONION_SENDFILE=0`) and/or keep alive (`onion_request_set_no_keep_alive(req)`)? If any of these work tell me to look closely. David.

i test biger than 2G mp4 file and can not play by browser(chome / edge)
add onion_request_set_no_keep_alive(req) same
but Local player can play
This problem is difficult for me.
because i don't know mechanism that browser how to play video
I test onion_response_write can play
onion_shortcut_response_file didn't work
but don't have Range function

thank you David
