I set up CSP on my apache backend server, there's several hash inside so the headers become quite big, I have the need to customize the proxy buffer size in the location
proxy_buffer_size 128k;
proxy_buffers 4 256k;
proxy_busy_buffers_size 256k;
Here where I found the solution:

Can you make a ticket on GitHub?
sure, well I will try, never did it :)
thx
