Remove Cookies From Static Resources for WordPress

It removes cookies from the requests to static resources for modern browsers.

When the browser requests a static resource such as an image, a stylesheet, or a script, it sends to the server all the cookies, and it does it at every request.

If your page requests 10 scripts, then it sends 10 times the cookies.

As you have probably heard, a way to solve this issue is to serve the static resources from a cookies-free subdomain.

The cookies-free subdomain is a possible solution, but sometimes you have no wish to create a subdomain only for the static assets and give instructions to WordPress for fetching them from the subdomain.

Moreover, why don’t we solve this issue directly at the root? Is the browser that sends cookies to the server, so let’s address this issue with the browser.

This is exactly what Remove Cookies From Static Resources does. It instructs the browser to don’t send its cookies when it requests static resources.

However, this solution will work only with the modern browsers that support the crossorigin attribute.

The plugin simply adds crossorigin=”anonymous” to all the requested scripts, links, and images. Nothing else.

This plugin will not work for old browsers. It will also not work for all those resources that are added with JavaScript, or CSS.

This plugin has no settings. No additional HTTP requests, no additional database queries. It consumes practically zero.

You should see an improvement in performance if yor website requests many static resources sending big data through the cookies.
