Variables $uid_got and $uid_set are only available after userid 
filter during sending headers.  This happens before ssi/xslt 
filtering (and of course logging), just after headers filter 
(which handles expires and add_header).

An attempt to use these variables before they are available will 
cache an empty value and you'll won't be able to see real values 
at all.
