description "This plugin extracts the value for the vary HTTP header. This is rarely useful however it does identify websites which filter based on the user-agent if 'user-agent' is present in the vary header. The vary HTTP header tells downstream proxies how to match future request headers to decide whether the cached response can be used rather than requesting a fresh one from the origin server. - More info: http://tools.ietf.org/html/rfc2616"
