It is bug in your session handler, but PHP should not behave that way.

Sorry, but further testing revealed when sess_read
return NULL;
for when nothing was found caused problems sometimes, not always!
However
return '';
seems to work all of the time!
Looks like sess_write has to return a '' (null string) It cannot return NULL, nor it
return false;
Otherise sess_write will never be called!

Problem solved in 4.1.0 (release).
All thanks to yohgaki@php.net for pointing me to his very well written code!
I found the reason my sess_write was never called with register_globals = off was because my
sess_read function was something like this:
sess_read( $key)
...
if I find stuff for $key from PostgreSQL {
return $valuesfound;
}
else {
return false;
}
The problem was with "return false;"
After changing:
return false;
to
return NULL;
things worked.
Don't know why the "return false" worked with "register_globals=on" and
"register_global=off" requires sess_read to return NULL if nothing was found...
THANKS again to yohgaki@php.net for his code and my apologise for wasting people's time.
Please feel free to close this bug report. I am not closing it because derick@php.net brought up
something which I don't know about nor can I duplicate.

Just to note that I can not reproduce this with latest CVS.
