By default, responses that feature a Vary header value of anything other than Accept-Encoding and a corresponding Content-Encoding: gzip header aren't cached on edge servers. Vary headers indicate when a URL's content varies depending on some variable, such as which User-Agent requests it. This behavior simply removes the Vary header to make responses cacheable.

Warning. If your site relies on Vary: User-Agent to customize content, removing the header may lead the edge to serve content inappropriate for specific devices.
