Study Notes
Understanding Cookies and Online Advertising
- Cookies can have an "expires=" parameter to specify when they should expire and be dropped.
- Overwriting cookies occurs when a new cookie with the same NAME, domain, and path as an existing cookie is encountered, resulting in the old cookie being discarded.
- There is no specific mechanism for deleting cookies, but a common hack is to overwrite a cookie with a bogus value and backdated or short-lived expires= to reset the expiration to the past.
- Some cookies may be marked with a special secure keyword, causing them to be sent over HTTPS only as a security feature.
- JavaScript can set and send cookies via the document object's "cookie" property, which maintains all defined cookies that can be read and written.
- Browsers need not store more than 300 cookies, nor more than 20 cookies per web server, nor more than 4K per cookie, and cookies can be removed when they expire or when the cookie file gets too large.
- Cookie values should not contain specific symbols and need to be encoded into their hex equivalents using escape(s) and unescape(s).
- Advertisers use cookies to target specific ads and track users through 3rd party cookies in online advertising networks.
- An online advertising network connects advertisers to websites that want to host advertisements and involves advertisers, website owners, ad networks, and visitors.
- Cookie-based marketing utilizes cookies and databases to create, maintain, and utilize consumer profiles to customize online advertising.
- Doubleclick, purchased by Google, is an Ad Network that uses cookies to customize ads based on user profiles.
- Google Analytics is a free web analytics tool that uses its own set of cookies to track visitor interactions, and visitors are not tracked across sites.
