Cookies and HTTP cookies

Today we have learned cookies which is part of our lecture. Let me put some ideas to distinguish between cookies and HTTP cookies Cookies are most commonly baked until crisp or just long enough that they remain soft, but some kinds of cookies are not baked at all. Cookies are made in a wide variety of styles, using an array of ingredients including sugars, spices, chocolate, butter, peanut butter or dried fruits. The softness of the cookie may depend on how long it is baked. BUT

HTTP cookies, more commonly referred to as Web cookies, tracking cookies or just cookies, are parcels of text sent by a server to a Web client (usually a browser) and then sent back unchanged by the client each time it accesses that server.Because they can be used for tracking browsing behavior, cookies have been of concern for Internet privacy. As a result, they have been subject to legislation in various countries such as the United States, as well as the European Union. Cookies have also been criticized because the identification of users they provide is not always accurate and because they could potentially be a target of network attackers. Some alternatives to cookies exist, but each has its own uses, advantages, and drawbacks.

According to Wikipedia there are some misunderstanding about cookies

1) Cookies are like worms and viruses in that they can erase data from the user's hard disks
2) Cookies generate popups
3) Cookies are used for spamming
4) Cookies are only used for advertising

Cookies are only data, not program code: they cannot erase or read information from the user's computer.

As discussed in our class, these cookies detect and stores Web user behaviours.

Various information can be collected in a profile of the web user.

More precisely, they cannot contain personal information unless the user has made it available to some sites. Even if anonymous, these profiles have been the subject of some privacy concerns.

According to the same survey, a large percentage of Internet users do not know how to delete cookies.

Please delete your cookies every time you log out you web browsers.

Hey Muneer,
I agree with your point. There are some misunderstanding of cookies.
Actually, cookies are very useful in affiliate marketing. Here cookies are something that tag's a visitors to an affiliate site and records the link that was the source of that visitors.
The cookies ensures that if the visitors belongs to or referred by a link from your website, that you will be creditated with the affliate sale.
It is just a snippet of data that is automatically placed on a visitors website and is totally harmless.
However, yes you do need to delete the cookies from your computer time to time.
