Description

Hello,

I have a "gzip" activated Nginx proxy server that is configured with "proxy_cache" directive and set to ignore vary headers at my side and a non Nginx upstream server running gzip enable mod at remote side however, I get doubled "Vary" header entry as it can be seen attached. What can cause this issue?

Thanks in advance

Best regards,

Likely that's because you have Vary header in a response, and you've added another one using the gzip_vary directive. Consider either removing upstream one with proxy_hide_header and/or switching off gzip_vary.
