[Zope] SQL Session first time load

Hi all, Is there a reason why you cannot query _ZSession on the first page access? Observe: <var header> <var contentstuff> <var footer> Header: call Session Footer use a ZSQL session that logs a pageload data including the PreciseTime as PK, and Zsession as foreign key and the page address with query string. What happens..: First time you load, you get a key error for _ZSession. To fix it: Reload page and all resumes as should. But I especially want to record the entry point for a browser... which cannot happen if only the second load can be logged. Paz
