[Zope-dev] Ensuring 'freshness' of dynamic pages (slightly offtopic)

2001-03-11 Thread Morten W. Petersen
Hi guys, I've been trying to ensure that documents from a certain website are always fresh, that is, every request for a new page must be validated before the client sees it. I've tried using these HTTP Cache-control directives: no-cache no-store max-age (1)

Hi Fred, The "export as files" paradigm is something we'd really like to see soon in Zope. We'd like it to be possible for objects to be asked for a "filesystem representation" of themselves and serialize their structures out to disk. This filesystem representation should be simple enough to

Hi Fred, I read the serialization proposal... yours is somewhere inbetween what we have now and where I think we're heading. I really like the format of your proposals! These should definitely go up on the fishbowl. One thing that I think is important for a FS serialization strategy is that
