Whenever you start a function using session_name('name') and then
session_start() the sessions name will automatically be the session name.
There is no need for those functions.
If you made your link like this: <a href="filename.php?<?=sid?>"> it tacks
on the name plus the session id. If cookies are enabled you will only see
the session id passed through the url on the first page.. After that you
wont, thus the little script I wrote so the '?' doesnąt show up. Now if
cookies arent enabled you will see the session name and id passed through
the url every single time. There is absolutely no reason to use those
functions since php takes care of that stuff for you.

blunders and absurdities have crept in; forget them as soon as you can.
Tomorrow is a new day; you shall begin it serenely and with too high a
spirit to be encumbered with your old nonsense." - Ralph Waldo Emerson
