Session id

I'm having a strange problem with the PHPSESSID value that's appended to url's automatically (the trans-id attribute is on). I have url's such as http://www.whatever.com/browse.php?cid=9&sid=0 on my front page, but now that the session id's are automatically appended, some of the links are now like http://www.whatever.com/browse.php?cid=9&sid=&PHPSESSID=22dcdd2fc728110a6fb64b7d542217290 and http://www.whatever.com/b?PHPSESSID=22dcdd2fc728110a6fb64b7d54221729rowse.php?cid=16&sid=62 It appears as if the session id is inserted in the middle of the url. The problem is very consistent since the problem links are exactly the same each time. Once I refresh the page or visit another page and come back, the problem is gone since the appended session id is no longer there. I have a session_start() call at the top of each page, because I use sessions for people to log in. Any help would be very much appreciated, Lenny http://www.internetplays.com/
