This is the prepend for all of my files:

// Start session
$s_permission = false;
@session_start();
session_register("s_permission");
$fallback = session_name()."=".session_id();

// Start output buffering
ob_start("ob_gzhandler");
ob_implicit_flush(0);

----

This is the footer:

ob_end_flush();

----

The script output works, but the session id is not added to any URLs (if cookies are set off for sessions). When I remove the output buffering things turn out fine and the SESSION-ID is added to the URLs. I've tried to add <?=SID?> on each URL, but that didn't help either. I invented a variable called $fallback, and add this to each URL, but this can't be a perfect solution, as without output compression this is not necessary.

Thanx
Daniel
