Subject Quick udat clarification
Date Sat, 12 Oct 2002 18:44:51 GMT
The docs say that so long as you don't touch udat, a session won't be 
created.  Then they are more specific and say so long as you don't 
*write* to udat one won't be created.  I just want to make sure that 
reading udat doesn't cause a cookie to be created (or hit the 
database).  I think that's the case, but I just wanted to double 
check.  Otherwise I can do what I do when I want to write to udat 
only if it already exists:
     $session = tied %$udat;
     return undef if (!$session);                # I don't think this happens
     $sessid = $session->getid();
     return undef if (!$sessid);                 # Won't create a session id

I'm trying to make sure that my site doesn't gratuitously create 
cookies until there's actually something that the user wants us to

I'm not sure which upsets me more: that people are so unwilling to accept
responsibility for their own actions, or that they are so eager to regulate
everyone else's.
