Hello,
Is anybody using streaming actions behind the Nginx proxy?
Let's say we have the following action:
stream_test ('GET', [], _) ->
StreamGen = fun
({N, Max}) when N < Max ->
{output,
list_to_binary ([ <<($A+(N rem ($Z-$A)))>>
|| _ <- lists:seq (1, Max) ]),
{N+1, Max}};
(_) ->
done
end,
{stream, StreamGen, {0, 64}}.
And just a "proxy_pass" rule on the Nginx side.
If I call the "stream_test" action directly, everything works fine. If I
try to call it via Nginx proxy, I get the error:
upstream prematurely closed connection while reading response header from
upstream
I have tried everything about the proxy buffer sizes, tried to toggle
buffering at all, tweaked most of the timeout options available, but none
of the mentioned helped.
(My tests are based on CB 0.8.7. Also tried to manually upgrade
ranch+cowboy to their latest versions. Didn't help.)
Any ideas?
Tom
