Download Specify a Vary: Accept-Encoding Header for WordPress V 1.0.0

Specify a Vary: Accept-Encoding Header is a free WordPress plugin designed to enhance website performance by adding a crucial HTTP header. Unlike many performance plugins that come with an array of unnecessary features, this tool focuses solely on its primary function, which is to append a 'Vary: Accept-Encoding' header to your server responses. This header plays a vital role in caching, ensuring that browsers receive the correct content based on the request they make.

The plugin operates by implementing a rewrite rule within the .htaccess file of your WordPress directory. This rule targets specific file types, such as JavaScript, CSS, XML, gzipped files, and HTML, ensuring that they are served with the appropriate Vary header. By optimizing how content is cached and served, users can experience improved loading times and better performance on their websites.
