It gives you a POSKeyError, when this is not the case. This sounds like what I'm looking for. Does it work something like the following? 1. Enter date at a particular place 2. Cookie is set 3. You can browse whereever you like at it will be exactly as it was Is it possible to have a look at the code? > >Also, is there an alternative to compacting the ZODB such that all that > >history could be archive offline but then reconnected when needed for view a > >snapshot? Does anyone have an idea of how hard this would be to do? Basically what I'm proposing is 1. Ability to mount two or more databases, each of which is the same DB just at a different slice of time e.g. 1 week 2. Ability to slice a DB in half. The back half is essentially rolled back and the front half is compacted so when joined they have the complete history. This way if they wanted to view diffs of pages or the whole site at a particular date then they just have use some admin interface to mount the right time period from backup storage and then just use your tool above or normal zope diffing. I think such a feature would be a real asset to zope in the corporate/government environment Dylan Jay --- http://www.meetmemap.com - makes giving directions easy http://www.pretaweb.com - Update-it-yourself, low cost websites http://www.eatmanifesto.com - against all dumbing down of food http://www.subjectivise.com/StockPhotography _______________________________________________ Zope-Dev maillist - [EMAIL PROTECTED] http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )
