Brief information about Third-party cookie
Third-party cookies are small pieces of code or text files that are stored on a user’s browser by a website other than the one they are currently visiting. These cookies are usually used for advertising and tracking purposes, collecting data about user preferences, online behavior, and interactions with various websites.
The History of the Origin of Third-party Cookie and the First Mention of It
Third-party cookies originated in the mid-1990s as an extension of the basic cookie technology. They emerged with the rise of online advertising networks, which needed a way to track users across different websites and provide more targeted advertising. Netscape Navigator was one of the first browsers to implement cookie technology, and third-party cookies quickly became a common tool for advertisers.
Detailed Information about Third-party Cookie. Expanding the Topic Third-party Cookie
Third-party cookies are created and stored by domains other than the one the user is visiting. They are often used by advertising networks to track user behavior across different websites, allowing them to build a profile of user interests. This can lead to more personalized and relevant advertising. Third-party cookies can also be used for analytics, social media integration, and other functions that require cross-domain tracking.
Key Functions of Third-party Cookies:
- Advertising Targeting: Enables the delivery of targeted ads based on user behavior and preferences.
- User Analytics: Collects data on user engagement and interaction across different websites.
- Cross-Site Authentication: Allows users to stay logged in across different domains and websites.
- Content Personalization: Enables customization of content based on user preferences and past interactions.
The Internal Structure of the Third-party Cookie. How the Third-party Cookie Works
Third-party cookies consist of a series of key-value pairs that store specific information. They contain:
- Name: Identifier for the cookie.
- Value: The information stored within the cookie.
- Domain: The domain that set the cookie and can read it.
- Path: Specifies the URL path that must exist for the cookie to be sent.
- Expiration Date: Determines when the cookie will be deleted from the browser.
- Secure Flag: Indicates whether the cookie requires a secure connection.
These cookies are sent from a third-party server to the user’s browser, where they are stored and sent back to the server with subsequent requests to that third-party domain.
