The Basics of Browser Cookies
Browser cookies were introduced to the web in order to keep persistent information about the user. The first use case was to check if a user had already visited Netscape’s website.
Cookies are strings that have a name field, a value field and additional optional attributes. The values are strings and you can store whatever you think is best for your application. Google Analytics’ _ga is probably one of || the most common cookie out there, it usually looks like this:
- Name: _ga
- Value: GA1.3.210706468.1583989741
- Domain: .example.com
- Path: /
- Expires / Max-Age: 2022-03-12T05:12:53.000Z
Cookies can store up to 4096 bytes of data (this includes name, value, domain, expiry date and whatever else you can fit in there). You can add a limited number of cookies per domain which changes depending on your browser.
