<DL>
<DD>Specifies the domain within which this cookie should be presented.

 <p>The form of the domain name is specified by RFC 2109. A domain
 name begins with a dot (<code>.foo.com</code>) and means that
 the cookie is visible to servers in a specified Domain Name System
 (DNS) zone (for example, <code>www.foo.com</code>, but not 
 <code>a.b.foo.com</code>). By default, cookies are only returned
 to the server that sent them.<DD><DL>

 when the Web browser exits. A zero value causes the cookie
 to be deleted.<DD><DL>

<PRE>
public void <B>setPath</B>(java.lang.String&nbsp;uri)</PRE>
<DL>
<DD>Specifies a path for the cookie
 to which the client should return the cookie.

 <p>The cookie is visible to all the pages in the directory
 you specify, and all the pages in that directory's subdirectories.

 for example, <i>/catalog</i>, which makes the cookie
 visible to all directories on the server under <i>/catalog</i>.

 information on setting path names for cookies.<DD><DL>
