Recently, my site’s vary header is showing “vary: Accept-Encoding,User-Agent,cookie”, the starge thing is I deactivated all the plugins, checked .htaccess file for both root and wp-content directory, nothing is found there.
So can you please guide me to the right direction that from where I can delete that thing?
I guess w3tc doing something wrong, may add that header but after uninstalling still it is showing same.
That vary header causing conflict with the CDN, that is why I want to remove that one.
Thanks in advance,
