Emergency Snoopy grab EMS verification Code, remote simulation query number, unable to obtain jsessionid of the relevant issues

Urgent: Use Snoopy grab EMS verification Code, remote analog query number, unable to get jsessionid problem?
Member life169 before in the PHP section of an article called ( use Snoopy crawl EMS verification Code, remote simulation query number, get query results)
Link is: http://topic.csdn.net/u/20100715/23/d58f2006-40ea-4cab-82e3-3bbcf4cd1e9f.html


But I encountered a problem in the process of testing, jsessionid, often will not be taken,

Session_Start ();
Include ("Snoopy.class.php");
$url = "Http://www.ems.com.cn/qcgzOutQueryNewAction.do?reqCode=gotoSearch";
$url 2 = "http://www.ems.com.cn/qcgzOutQueryNewAction.do";

$snoopy = new Snoopy;
$snoopy->fetch ($url); Get all content
Print_r ($snoopy->headers);

The print header information, which is returned:
Array ([0] = http/1.1-OK [1] = content-type:text/html; charset=gb2312 [2] = = x-powered-by:servlet/2.4 JS p/2.0 [3] = accept-ranges:bytes [4] = connection:close [5] = Date:tue, [Mar] 11:24:53 GMT [6] = A ge:1876 [7] = content-length:22804)

The correct return information should be:
Array ([0] = http/1.1-OK [1] = cache-control:no-cache= "Set-cookie" [2] = connection:close [3] = Dat E:fri, Mar 07:42:04 GMT [4] = content-type:text/html; charset=gb2312 [5] = set-cookie:jsessionid=n5sms1dmw1wy8lj48z1zhp1p2ks1gsgy5twtnxcypz1mvgyzk0lq!195316506; path=/[6] = x-powered-by:servlet/2.4 jsp/2.0)

The back of the inside no jsessionid, resulting in the query in the back of the query results can not be returned, I have been the whole 2 days, in the Internet to check a large amount of information, or no clue, there is now a strange phenomenon, If the browser opens the Ems.php page, after a period of time and then refresh the page, will return the correct headers information, but after a while can not be returned correctly, why this situation, I hope that there are prawns can help me see what is going on?
