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 <code>.htaccess</code> Apache file.
<pre><code>< IfModule mod_headers.c >

 < FilesMatch \".(js|css|xml|gz|html)$\" >

 Header append Vary: Accept-Encoding

 < /FilesMatch >

< /IfModule >
</code></pre>

Specify a Vary: Accept-Encoding Header

This plugin fixes a "Vary: Accept-Encoding Header" message and boosts website performance.
