How Cookies Work
Let us use an example of registering at a social networking site to explain how cookies work in a system. A user submits information, like name, age, gender, and date of birth to the web server of the original site. Cookies, which are small pieces of information, are used by web servers to send back the information to the web browser, so that the next time the same user logs in, he or she doesn’t have to key in the same information shared previously.
Cookies in Joomla
Cookies are used in Joomla to track the activities and store submitted information by a user. They make Joomla a user-friendly content management system because navigating from one page to another, back and forth, has been made convenient and easy with Joomla cookies. Although users have the discretion not to accept cookies, they should not worry about their accounts being hacked because the chances are low since most of the information is encrypted.
