Specify A Vary: Accept-Encoding Header Wordpress Plugin - Rating, Reviews, Demo & Download
Plugin Description
Many WordPress performance plugins are bloated and include features that you don’t need. This plugin does just one thing. It adds a “Vary: Accept-Encoding Header” to boost website performance.
When browsers make a request, they include HTTP headers for the server to decide what to send back. The Vary header describes what information identifies a request. Caches should only be used if the request matches the Vary information in the cache.
This plugin adds a rewrite rule to your WordPress directory’s .htaccess
Apache file.
< IfModule mod_headers.c >
< FilesMatch ".(js|css|xml|gz|html)$" >
Header append Vary: Accept-Encoding
< /FilesMatch >
< /IfModule >
