What Are HTTP Cookies?<\/h2>
HTTP cookies are text files containing data components a website sends to the users’ web browser, such as login authentication and language preferences, to improve user experience.<\/p>
When you access a site with cookies for the first time, the site sends a request to your browser to store its cookies. The browser then stores this data, which helps the site provide a personalized browsing and online advertising experience based on previous visits.<\/p>
However, the information it will collect depends on the website’s needs. For example, an eCommerce website<\/a> usually uses cookies to track your purchase history and shopping cart items.<\/p> The next time you visit it, the cookies stored will help the site recommend products or display ads according to your previous activity.<\/p> When an HTTP request is made, the browser sends data and response headers to the site’s server. Some of these might include Set-Cookie<\/strong> headers, which tell the browser to set certain cookies.<\/p> Since static content like images, JavaScript<\/a>, and CSS files rarely change, sending those cookies will do nothing but clog the web server with unnecessary network traffic ‒ causing your site to slow down.<\/p> A cookie-free domain is a domain that doesn’t send the browser a request to store the site’s cookies. Using this domain type will reduce the number of requests sent to the server since it will not send cookies for content that doesn’t need them.<\/p> Consequently, it will improve your website’s performance, eliminating unnecessary traffic.<\/p> There are two methods you can use to set a cookie-free domain. The first one requires creating a separate domain to deliver the static content. That’s because if you use a domain like yourwebsite.com<\/strong>, the cookies will be set in all your subdomains as well.<\/p> However, if you use a regular domain like www.yourwebsite.com<\/strong>, you only need to create a cookie-free subdomain. To use a cookie-free domain on your WordPress website<\/a>, simply follow these steps:<\/p> Ensure these lines are placed above the \/* That’s all, stop editing! Happy publishing. *\/<\/strong> line. Placing them below this line may result in the settings not being applied correctly.<\/p> Once that’s done, static.yourwebsite.com will deliver all static content without cookies.<\/p> Another way of using a cookie-free domain is to set up a content delivery network<\/a> (CDN) like KeyCDN<\/a> and Cloudflare<\/a>.<\/p> If you use KeyCDN, enabling the Strip Cookies<\/strong> feature will stop the server from sending Set-Cookies<\/strong> headers in response to HTTP requests. The Cache Cookies <\/strong>setting allows users to ignore all cookies.<\/p> This will help the website load faster, and the user will no longer get the cookie-free error.<\/p> Cookie-free domains are an essential part of website optimization efforts – even GTmetrix includes in its scoring metrics. GTmetrix displays a cookie-free error for websites that don’t use a cookie-free domain as their server is deemed unoptimized, harming the site’s overall score.<\/p> Using cookie-free domains can bring several benefits for your website, including:<\/p> When analyzing your site’s performance using a tool such as GTmetrix, you might have found the cookie-free error. It might seem complicated at first, but it is not difficult to solve it – you can set a cookie-free subdomain or change your CDN settings.<\/p> We hope this article helped you learn what cookie-free domains are and how to set them up on WordPress to improve your traffic, SEO, and user experience.
