/**
 * This cookie comparator ensures that multiple cookies satisfying 
 * a common criteria are ordered in the Cookie header such
 * that those with more specific Path attributes precede those with
 * less specific.
 *  
 * 
 * This comparator assumes that Path attributes of two cookies 
 * path-match a commmon request-URI. Otherwise, the result of the
 * comparison is undefined.

 * @deprecated Jakarta Commons HttpClient 3.x is deprecated in the Jenkins project.
 *  It is not recommended to use it in any new code.
 *  Instead, use HTTP client API plugins as a dependency in your code.
 *  E.g. 
 *      Apache HttpComponents Client API 4.x Plugin or
 *  Async HTTP Client Plugin.
