It looks like this can be done in Nginx configuration by using proxy_cookie_path, but in /opt/zimbra/conf/nginx I see a ton of configuration files in the directories there, and I am not sure which one(s) I need to edit, or if I am looking in the wrong place altogether. Some links that I am reading say to look for ssl.conf or default.conf, but Zimbra doesn't seem to use either of these files. Can anyone point me in the right direction? I am using Ubuntu 18.04 and Zimbra 8.8.6_GA_1906 OSE. Thanks in advance for any help!
