Cookies
noun · web
Small data files stored by the web browser on the user's device when visiting a website, allowing it to remember information such as browsing preferences, login status, or shopping cart contents.
A technical mechanism of the HTTP protocol that compensates for the stateless nature of the web by enabling servers to identify and track users across different pages and visits to a website.
A central element of the web's advertising and analytics ecosystem, subject to the user's explicit consent under the GDPR and the ePrivacy Directive — requiring rigorous technical management through compliant consent banners.
Yes, European regulations (GDPR and ePrivacy Directive) guarantee every user the right to refuse non-essential cookies. Only cookies strictly necessary for the site to function (authentication, shopping cart) may be set without consent. At Async Code, we develop compliant consent banners that respect the user's choice and effectively block trackers when consent is refused, ensuring your site's legal compliance.
An HTTP cookie is a small text file sent by a web server to the user's browser via the Set-Cookie header of the HTTP response. It is stored locally and automatically sent back to the server with each subsequent request, allowing a session state to be maintained. Our agency configures HTTP cookies with the appropriate security attributes (Secure, HttpOnly, SameSite) to protect your users' data against XSS and CSRF attacks.
A cookie is a small data file that a website saves on your device (computer, smartphone, tablet) through your browser. It is used to remember your preferences, login session, or browsing choices to improve your user experience. Async Code implements transparent, GDPR-compliant cookie management in every web project, with a clear distinction between functional, analytical, and advertising cookies.
Internet cookies are small text files placed on a user's device by the websites they visit. They contain key-value pairs that identify the user, personalize their experience, and measure site traffic. There are several categories: session cookies (temporary), persistent cookies (set duration), and third-party cookies (set by external domains). Our agency masters these distinctions to configure each cookie optimally.
Cookies are not inherently dangerous because they cannot execute code or carry viruses. However, third-party cookies used for advertising tracking can compromise privacy by reconstructing a user's browsing history across different websites. The real risk lies in poor technical configuration. At Async Code, we secure our clients' cookies with the HttpOnly, Secure, and SameSite flags to prevent any hijacking.
The role of a cookie is to allow a website to remember the user between different pages and visits. Functional cookies maintain the login session and preferences. Analytics cookies measure audience and visitor behavior. Advertising cookies enable targeting and retargeting. Our web agency precisely categorizes each cookie and implements a granular consent system compliant with regulatory requirements.
Internet cookies are digital trackers used by virtually all websites to function properly and analyze their traffic. They enable experience personalization (language, theme, geolocation), the maintenance of secure sessions, and performance measurement through tools like Google Analytics. Async Code configures each project's cookies in compliance with the GDPR's data minimization principle, collecting only the strictly necessary information.
Cookies become problematic when they are used abusively for cross-site tracking, allowing ad networks to build detailed user profiles without informed consent. Unsecured cookies can also be intercepted through man-in-the-middle attacks on unencrypted connections. Our agency combats these risks by exclusively implementing secure cookies (HTTPS), limiting their scope, and offering privacy-friendly analytics solutions.
Deleting cookies is done through your browser settings: in Chrome, go to Settings > Privacy and Security > Clear Browsing Data. In Firefox, go to Settings > Privacy & Security > Cookies and Site Data. You can also configure your browser to automatically block certain types of cookies. At Async Code, we design our sites to work optimally even when non-essential cookies are deleted or refused.
Cookies on websites are technical mechanisms that allow a site to store and read information in your browser. When you visit a site, it can set cookies to remember your preferred language, keep you logged in, or anonymously analyze traffic. European legislation requires every site to display a consent banner for non-essential cookies. Async Code develops high-performance, compliant cookie management platforms (CMP) for every web project.
