After I added some CORS headers to my API, one of the users of my nginx-based system complained about occasional errors with:
upstream sent too big header while reading response header from upstream He also reported to have worked around the issue using: proxy_buffers 8 512k; proxy_buffer_size 2024k; proxy_busy_buffers_size 2024k; proxy_read_timeout 3000; However unfortunately I was unable to reproduce this problem myself. I also had a hard time figuring out what the exact problem is. Some questions: - What exactly does this error mean? Does it mean that response contained too many headers? How many is too many? - Is it wise to increase the buffer sizes as the user reported? What would be sensible defaults? _______________________________________________ nginx mailing list [email protected] http://mailman.nginx.org/mailman/listinfo/nginx
