     38  * This cookie comparator ensures that multiple cookies satisfying
     39  * a common criteria are ordered in the <tt>Cookie</tt> header such
     40  * that those with more specific Path attributes precede those with
     41  * less specific.
     42  *
     43  * <p>
     44  * This comparator assumes that Path attributes of two cookies
     45  * path-match a commmon request-URI. Otherwise, the result of the
     46  * comparison is undefined.
