output buffering messing with sessions

[jackvull]

Hi
I had a recent problem with the session not being propagated across page requests.
I'm pretty sure this has been cause by output buffering because when I flushed the buffers and then made direct requests for a page I was logged in with the correct session.

Only, I'm not sure how to go about fixing this when I have buffering in place.

I use a logon script, which changes the session ID when the user authenticates and at the end of the logon script, it has a header call to redirect them. Only because of the way header calls work, sent at the beginning of the request, it picks up the old session ID.

Any ideas?

Thanks.

I use output buffering quite often with sessions without issue. However, that doesn't mean you and I do things in the same order ;)

Can you give a simple flow of your steps? For example, is it ...

1. Start session
   
2. Start output buffering
   
3. End output buffering
   
4. Change session id

?

I do
Start output buffering
Start session
Change session id
End output buffering

although the header call I use is called before I use ob_end_flush(); and exit();
