What is a cookie?
Cookies are often indispensable for websites that have huge databases, need logins, have customizable themes, other advanced features.
Cookies usually don't contain much information except for the url of the website that created the cookie, the duration of the cookie's abilities and effects, and a random number. Due to the little amount of information a cookie contains, it usually cannot be used to reveal your identity or personally identifying information.However, marketing is becoming increasingly sophisticated and cookies in some cases can be agressively used to create a profile of your surfing habits. There are two types of cookies: session cookies and persistent cookies. Session cookies are created temporarily in your browser's subfolder while you are visiting a website. Once you leave the site, the session cookie is deleted. On the other hand, persistent cookie files remain in your browser's subfolder and are activated again once you visit the website that created that particular cookie. A persistent cookie remains in the browser's subfolder for the duration period set within the cookie's file.
More on Cookies
A cookie is a small file of letters and numbers downloaded on to your computer when you access certain websites. Like virtual door keys, cookies unlock a computer's memory and allow a website to recognise users when they return to a site by opening doors to different content or services. Like a key, a cookie itself does not contain information, but when it is read by a browser it can help a website improve the service delivered.
Cookie files are automatically lodged into the cookie file - the memory of your browser - and each one typically contains:
• The name of the server the cookie was sent from
• The lifetime of the cookie
• A value - usually a randomly generated unique number
Are all cookies the same?
There are two types of cookies:
Session cookies - these are temporary cookie files, which are erased when you close your browser. When you restart your browser and go back to the site that created the cookie, the website will not recognize you. You will have to log back in (if login is required) or select your preferences/themes again if the site uses these features. A new session cookie will be generated, which will store your browsing information and will be active until you leave the site and close your browser. More on session cookies.
Persistent cookies – these files stay in one of your browser's subfolders until you delete them manually or your browser deletes them based on the duration period contained within the persistent cookie's file (more on persistent cookies).
