## Description

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.
 In all other cases you don’t need
this plugin, as you would not need to serve static resources from a cookies-free
domain. Removing cookies from static resources is not always the performance saver
that some people think. This is totally not true in many cases. In most cases the
cookies aren’t the cause of bad peformance, but the resources itselves. In those
cases, it would be more effective totally removing the resources that you don’t 
need everywhere with [Freesoul Deactivate Plugins](https://wordpress.org/plugins/freesoul-deactivate-plugins/).

Of course, removing cookies from static resources improves also the privacy of your
visitors.

As a side note, removing cookies form static resources with this plugin will have
no impact on the score given by some speed meters.
 The speed meters only check 
if the static resources are requested to free-cookies domains, but they don’t check
the crossorigin paramenter.

### 󠀁[How to remove cookies from static resources](https://josemortellaro.com/remove-cookies-from-static-resources/)󠁿

 * Install Remove Cookies From Static Resources
 * Done!

### How to understand if I really need to remove cookies from static resources

 * Go to your website
 * Right-click => Ispect => Console => write document.cookie.length and press enter
 * If you see a number higher than 5000 you probably need this plugin to save bandwidth
   due to big data transfers through the cookies. For lower numbers you will probably
   not need this plugin.

### Does removing cookies from static resources always improve the performance?

Absolutely not! It improves the performance only if yor website requests many HTTP
requests due to static resources and it writes many data to the browser through 
the cookies.

### Limits

 * This plugin doesn’t work for old browsers that don’t support the crossorigin 
   attribute
 * This plugin doesn’t work for all those resources that are added with JavaScript
   or CSS, and probably it will never work in those cases, neither with future versions
   of the plugin.

Recently we started using WordPress as a headless platform, and it’s so odd that
WordPress has this behaviour of applying cookies on static files.This plugin does
what it says it does, Simple small and short code which works well.
