875	Vary Header Duplicate	omer.ozdemir.nemeroth.com@…		"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
