Cookie is a small piece of information being stored by web browser on a machine where this browser runs. Cookie may contain (not all of it is required) its name, its value (this is usually a text string with some information or simply some number), the web domain name to which this cookie belongs, relative path to the domain name (which path is called URI) where this cookie is active, the date when this cookie expires and should be deleted (if the date is not set, the cookie will be deleted when you shut down your web browser), and, finally, a special flag "secure", which shows if this cookie shall be transmitted by secured protocol or not. Cookies are mostly used to remember some piece of information, which may be useful while user is browsing a web site.
Let's see an example of cookie, which is stored by this web site, when you press OK button after the notice regarding to cookies.
It looks like this:
MHcom_cookies_notice_read=1; expires=Wed, 03 Jul 2019 19:35:01 GMT; path=/; domain=.magic-horoscope.com
What's this cookie used for? This cookie, being read by your web browser and transmitted to our web server, tells to the server that you did already confirm that you have read the notice about cookies and the page shall not contain this notice again.
How's that? This part "MHcom_cookies_notice_read=1;" is the name of the cookie and its value. The name is chosen so that we can simply recognise what's this cookie used for, and the value of 1 is equal to YES, IT IS READ.
Next part "expires=Wed, 03 Jul 2019 19:35:01 GMT;" shows when the cookie shall be deleted. In our case this notice is viewed and confirmed on 3rd of July 2018 and the period of cookie validity is set to 1 year. After that date web browser will not find this cookie and therefore our pages will show the notice about cookies again.
This part "path=/;" tells to web browser that this cookie is valid for all the pages of this domain. "/" is the root directory, also in general it represents a main page of a web site, i.e. the page that is loaded when you enter only the domain name in your web browser (for examle magic-horoscope.com).
And, finally, "domain=.magic-horoscope.com" is obviuosly the name of the domain this cookie belongs to. So this cookie is only read by browser when requested from this web site. Also, each browser sets its own cookies. One browser can't read cookies which were set by other browser.
We do not use "secure" flag for this cookie, since this cookie's information obviously is not sensitive neither for user nor for web site.
By the way, a security. On its own the cookie represents nothing else but the piece of text string, it can not be executed as an application or start any action by itself. So it can not represent a direct danger like a virus or something similar. There may be some subtlety when cookies are used miscorrectly. The example of such wrong action is storing someone's password directly as cookie's value, which password is used for authentication to some web site. This may represent some danger to safety of user's data, stored at that web site, because intruders can steal information from cookie.
The one described above is the first and only cookie being set by this web site directly, and it shows if user have confirmed that he has read notice about cookies or not.
