What are cookies?
Cookies are small text files stored on your computer when you visit particular web pages. When you revisit the website later or visit a different webpage, a copy of the cookie file is sent to the website.
They can be used to store information and have many uses, with the most common being tracking, remembering your details or settings, and keeping you logged in to an account.
When are cookies created?
Writing data to a cookie is usually done when a new web page is loaded. For example after a ‘submit’ button is pressed, the data handling page would be responsible for storing the values in a cookie. If the user has elected to disable cookies then the write operation will fail, and subsequent sites which rely on the cookie will either have to take a default action, or prompt the user to re-enter the information that would have been stored in the cookie.
Why are cookies used?
Cookies are a convenient way to carry information from one session on a website to another, or between sessions on related websites, without having to burden a server. Storing the data on the server without using cookies would also be problematic because it would be difficult to retrieve a particular user’s information without requiring a login on each visit to the website.
If there is a large amount of information to store, then a cookie can simply be used as a means to identify a given user so that further related information can be looked up on a server-side database. For example, the first time a user visits a site, they may choose a username which is stored in the cookie, and then provide data such as password, name, address, preferred font size, page layout, etc. This information would be stored on the database using the username as a key. Subsequently when the site is revisited, the server will read the cookie to find the username, and then retrieve all the user’s information from the database without it having to be re-entered.
- Session cookies, which are automatically deleted after every visit.
- Persistent cookies that will remain in place during multiple visits to the site.
- Third party cookies, which are used by partner websites that are embedded within our site or that we link to.
