session.cookie_domain problem

I have a small application that uses adodb and session for user management. The sessions are managed through the use of adodb-session-clob.inc.php. The code snippet below shows what I do related to sessions (minuse some variable assignment). $cookie_domain is set to '.whatever.com' However, when I try to assign a cookie domain neither mozilla or ie will accept the cookie as I would expect they should. Konqueror on the other hand does accept it just fine. If I comment out that line, the cookie is properly established by all browsers, but only for that one particular host instead of for the domain. I have searched around for this for a few days in the mailing lists and bug db, but haven't really found a solution. I did see a message from one other person about this quite some time ago, but there was never a response to that person's inquiry. Does anyone have any idea what I am doing wrong, or is this a known issue Thanks, Dustin // Set session parameters and start session ini_set("session.gc_maxlifetime", "172800"); ini_set( "session.entropy_file","/dev/random"); ini_set( "session.entropy_length","512"); ini_set( "session.name",$session_name); ini_set( "session.cookie_domain", $cookie_domain); session_start();
