Cookies are files, often including unique identifiers, that are sent by web servers to web browsers, and which may then be sent back to the server each time the browser requests a page from the server.
Cookies can be used by web servers to identity and track users as they navigate different pages on a website, and to identify users returning to a website.
Cookies may be either "persistent" cookies or "session" cookies. A persistent cookie consists of a text file sent by a web server to a web browser, which will be stored by the browser and will remain valid until its set expiry date (unless deleted by the user before the expiry date). A session cookie, on the other hand, will expire at the end of the user session, when the web browser is closed.
Cookies are very important to improve the users’ experience. If cookies would not exist, the experience would not be so gratifying.
Different kinds of cookies for different uses
We use different kinds of cookies within Google sites. The following cookies can be found in your navigator when using our blog:
- Preferences: they remember information about personalization, such as language or region where the visit has been done. Deactivation of this cookie should not affect to the using of our blog.
- Security: secure cookies are used in order to prevent a fraudulent use of initial credentials and in order to protect users from non authorized foreign users.
- Process: The main purpose of this kind of cookies is to identify users and possibly prepare customized Web pages or to save site login information for you. When you enter a Web site using cookies, you may be asked to fill out a form providing personal information; like your name, e-mail address, and interests. This information is packaged into a cookie and sent to your Web browser, which then stores the information for later use. The next time you go to the same Web site, your browser will send the cookie to the Web server. The message is sent back to the server each time the browser requests a page from the server.
A Web server has no memory so the hosted Web site you are visiting transfers a cookie file of the browser on your computer's hard disk so that the Web site can remember who you are and your preferences. This message exchange allows the Web server to use this information to present you with customized Web pages. So, for example, instead of seeing just a generic welcome page you might see a welcome page with your name on it.
