PHP session variable & PHPSESSID

Hi all, I am having an error in getting the session variable in php:

1. my application is a login page, if user successfully logged in, the user id will become sessioned and then he will be directed to the main page. I don't know why there are "?PHPSESSID=xxxxxxxx" in all URL of the main page...

I have tried some similar application in another server, but the PHPSESSID should not be shown... how can I make this invisible??

2. in each of the main page link, I redirect the user to a frame page, but it seems that the frameset cannot get the sessioned variable....I can only get the variable if I open another browser at the same time and login again...(in this double login case, I will not get "?PHPSESSID=xxxxxxxx" at the end of the main page link)

Hope someone can help, thanks

what it does is it appends the session variable to each hyperlink ti see on the page. You can disable that for hyperlinks or you can switch to having session via cookies which dont require the session to be passed via anu URlL.

it looks like the session.use_trans_sid is enabled on your system. Then PHP adds that part if no cookie can be set.

; trans sid support is disabled by default.
; Use of trans sid may risk your users security.
; Use this option with caution.
; - User may send URL contains active session ID
;   to other person via. email/irc/etc.
; - URL that contains active session ID may be stored
;   in publically accessible computer.
; - User may access your site with the same session ID
;   always using URL stored in browser's history or bookmarks.
session.use_trans_sid = 0

So disable session.use_trans_sid if it is enabled.
