[Zope-dev] Caching

[Josh Zeidner]

Hi Damien,

  I solved this problem for a web-site( S&S ) based in Cold-Fusion by 
simulating browser requests and copying the contents retrieved into a cache 
directory structure.  The caching took place on a time-bases rather than 
some function of hits or timestamp.  I do not know, however, if this caching 
mechanism could be developed( to work efficiently ) as part of Zope as any 
object in Zope is dynamically created.  I good idea may be to write a simple 
web-spider that tracks the contents of the site and automatically caches all 
the pages on a regular basis...
