Code Forums - View Single Post - Keeping sessions unique when someone links with SESSID?

i don't get it, .. why do you even use the session id in the url? session_id() returns the current session id. take this code for example, it will only start a session if a session_id does not exist:

PHP Code:

  <?

if( !session_id() ){

  session_start();

}

?>

it seems like if you just went by session_id() instead of the url session id, it would be fine. am i missing something?
