 * DAVServlet rolls its own session cookie because the Servlet container's
 * session <em>cannot</em> be constrained to use ONLY cookies and NOT
 * URL-rewriting, and the latter would break the DAV protocol so we cannot
 * use it. Since we really only need to cache the authenticated EPerson (an
 * integer ID) anyway, it's easy enough so simply stuff that into a cookie.
 * <p>
 * Cookie format is: <br>
 * {timestamp}!{epersonID}!{client-IP}!{MAC} <br>
 * where timestamp and eperson are integers; client IP is dotted IP
 * notation, and MAC is the hex MD5 of the preceding fields plus the
 * "cookieSecret" string. The MAC ensures that the cookie was issued by this
 * servlet.
 * <p>
 * Look for authentication cookie and try to get a previously-authenticated
 * EPerson from it if found. Also check the timestamp to be sure the cookie
 * isn't "stale".
 * <p>
 * NOTE This is also used by the SOAP servlet.
 * <p>
 *
