What are cookies and how do they work?
"Cookies" are text-only pieces of information that a website transfers to an individual's hard drive or other website-browsing equipment for record-keeping purposes. Cookies allow the website to remember important information that will make your use of the site more convenient. A cookie will typically contain the name of the domain from which the cookie has come, the "lifetime" of the cookie, and a randomly generated unique number or other value. Like most websites, we use different categories of cookies for a variety of purposes in order to improve your online experience.
Depending on the purpose, we use 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).
How can I block and/or delete cookies?
Use the options in your web browser if you do not wish to receive a cookie or if you wish to set your browser to notify you when you receive a cookie. You can easily delete any cookies that have been installed in the cookie folder of your browser.
