Vary: User-Agent

Let’s take a look how the most commonly used value, User-Agent, works. It tells our Dynamic caching: “Hey, you should store different caches for different OS and browsers”. This is done in order to avoid serving a cached desktop version to a mobile visitor for example. Note, however, that nowadays most of the sites don’t actually serve different HTML for their mobile versions. It’s the responsive CSS that does all the heavy lifting and shows your site in a different way on mobile and on desktop. So, unless you’re using a plugin like WP Touch for example, or you know for sure you have a difference in the HTML output of your site, based on visitors browsers, your site should not be sending the Vary: User-Agent header.
