Many websites use "persistent cookie" technology. A persistent cookie is a small text file that this website places on your web browser so that it can collect anonymous summary demographic information, and remember your browser when it is used to visit our site again later—kind of like cookie crumbs! (Hence the name.) These cookies uniquely identify a browser on a computer, but never a person. In other words, if the same person utilizes Chrome and Internet Explorer, two unique browser cookies will be assigned, one for each browser, so that person well be counted as two different guests because visits are based on browsers, not computers or persons. Most Internet browsers automatically accept persistent cookies. Although utilizing persistent cookies generates a much better experience for you while visiting the site, most sites will also work without them. If you don't want to accept cookies, you can edit your browser's options to stop accepting persistent cookies or to prompt you before accepting a cookie from the websites you visit. Below you'll find directions to help you disable cookies in some of the more popular desktop browsers and mobile browsers.
Important: If you choose to set your browser to reject cookies from every website you visit, this is likely to adversely affect the functionality of non-government websites you visit.
