Hello, Can somebody give me a hint for what am I doing wrong with my setup. I have Zope instance that is proxied by nginx (doing address rewriting) that I want to be cached by varnish, but as soon as I configure Zope to add Accept-Language to Vary header, varnish starts closing connection when asked for object from Zope without returning any data. I'm using default.vcl
Using tcpdump doesn't reveal anything useful, the only difference is Accept-Language value in Vary header. Request that works: # GET -H "Host: hostname.domain.tld" -Used http://hostname.domain.tld GET http://hostname.domain.tld Host: hostname.domain.tld User-Agent: lwp-request/5.834 libwww-perl/5.836 200 OK Wide character in print at /usr/local/bin/GET line 439.
