You may have heard that cookies are "bad" and that Federal sites are not permitted to use them. That statement is partially true. There are two types of cookies: persistent and session cookies. "Persistent" web cookies are defined as web cookies that can be used to track "the activities of users over time and across different web sites." We do not use this kind of cookie.

Session cookies, the kind used on this site, automatically expire when users leave a site. Session cookies retain information only during the session or for the purpose of completing a particular online transaction, without any capacity to track users over time and across different web sites.
