Session Id's

[Anon]

Have a question on setting session id's. We have a windows client application which receives the session id (aka PHPSESSID). On subsequent requests the app will send back to the server this variable.

What i would like to know is which is the proper way to set the session id using session_id before or after the session_start();??

thanks

i don't quite follow, what is it you are trying to do?

I'm trying to "load" the session that contains variables registered during that session.
The windows client sends some variables to a php script, e.g. send.php. On the first line of send.php, there is session_start(). The server sends back a header, Set-Cookie : PHPSESSID=XXXX;. After doing some processing on the variables, other variables are registered. The windows client "saves" this string (PHPSESSING), and passes it on subsequent connects to the php script. The php script "should" take this PHPSESSID and use it in a session_id() to "load" the session.

So my question is do I do this call to session_id before or after a session_start()?
