A cookie is a text-only string of information that a website transfers to the cookie file of the browser on the hard disk of computers so that the website can remember who you are.
A cookie will typically contain the name of the domain from which the cookie has come, the "lifetime" of the cookie, and a value, usually a randomly generated unique number. Two common types of cookies are used on most websites-session cookies, which are temporary cookies that remain in the cookie file of your browser until you leave the site, and persistent cookies, which remain in the cookie file of your browser for much longer (though how long will depend on the lifetime of the specific cookie).
There are two types of cookies: session cookies and persistent cookies.
Session cookies are created temporarily in your browser's subfolder while you are visiting a website. Once you leave the site, the session cookie is deleted. On the other hand, persistent cookie files remain in your browser's subfolder and are activated again once you visit the website that created that particular cookie. A persistent cookie remains in the browser's subfolder for the duration period set within the cookie's file.
When someone visits our website we collect standard internet log information. We do this to find out things such as the number of visitors to the various parts of the website and we also allow cookies to be set by independent measurement companies like Google Analytics. We collect this information in a way which does not identify anyone.
