What you need to know about cookies
What are cookies?
Cookies are small portions of text information which web server delivers to your web browser in order to save some data about your current session. Browser will store this information in special files and deliver it back to the server every time you visit this site again.
Why are cookies used?
Cookies help to solve the problem of impermanent connection between client and server. It means that server “forgets” all the info you have already entered and you should input it again and again after every site reloading because server will perceive you as a new user. However, if cookies are used, your web browser will save this info and “remind” it to server every time.
What can be done with the cookies’ help?
Cookies are also used in webshops for virtual shopping cards. With its help server memorizes what customer wants to buy and creates an order.
And finally, cookies can be used for marketing and promotion as well. Many websites contain different adverts from third-party sites. These third-party sites are able to analyze some info stored in cookies, e.g. about viewed by user items, visited by him/her websites or his/her geolocation. So, having analyzed such info, advertisers may show to users advertising based on their interests, location or any other indicators. It’s not a secret that targeted adverts are more effective than usual, so cookies may help to increase the amount of customers.
Cookies are not dangerous by themselves, but as far as a lot of users’ personal info is contained on commercial web servers, there always exists a risk that this info may be stolen. So, it’s better to control the information you save in a cookie file. All the modern websites are able to manage cookies acceptance or even block it at all. Moreover, there are a lot of Cookie Managers which will allow you to control all the cookie-related processes. So, cookies may be absolutely safe if you use it properly.
