iis7,iis7.5 in the high version of IE lost session, each refresh page, will generate a new SessionID

The test script is Php,ie version IE9, the other kernel browser Ff,chrome,safari does not have this problem.
Found this problem, is to do a login page, using $_session to judge, IE is not logged up, other browsers no problem.

After testing the print session_id(); next time, ie refresh the page value is different, open d:\tmp\session (this is the php.ini inside the session storage location), each refresh to add a session file, of course, this does not exist under other browsers.

Later, a temporary solution is to set a cookie on the PHP page

session_start();setcookie('PHPSESSID',session_id());

It's a temporary settlement, but ... Eggs or continue to pain, the server (win2008 x86 IIS7 fastcgi php5.2.17nts) put a drupal, often people respond to login not, do not guess, it is definitely not with IE, this thing annoyed me ah, I do not want to change Drupal ... Anyway, for a few months, I've been looking for answers.

Now, the answer is not so important, just hope there is a solution, please walk past friends, give your experience, help me this stray lamb.

By the way, on the way to find the answer, I found a problem with the same person, but the solution I did not understand, because to be sure, my domain name is not underlined. Http://forums.iis.net/t/1150171.aspx Please understand this post of friends, also give advice.

Oneself to the knot paste, finally found out where the problem, it is really my fault.
Because I put a variable inside the php.ini: Session.cookie_path the meaning of the wrong understanding, filled into d:\tmp, so we can not log in. Now it's normal to change to empty.

Add:
session.cookie_pathRefers session to the site domain in effect;
session.save_pathRefers session to the path where temporary files are stored.
