RE: [Zope-dev] ClientCache and Large Files
This sounds like the most appropriate solution, as long as you are careful to make sure that Squid or other forward cache is configured to cache files that large, it isn't likely going to be by default.

You're best bet would be to put a proxy cache in front of Zope. Zope's not very efficient at serving big static files like this compared to Apache or squid. > I'm afraid not; this isn't a very typical use case.

I think it would be nice to be able to control cacheability of certain objects. However it smells like a YAGNI, especially with good front end caches that can take care of it. -Casey ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope ) ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

You could implement a file size limit, or increase the cache size to be more than twice the largest expected dowload (the cache is implemented as two files, each of which is limited to half the nominal cache size). --Guido van Rossum (home page: http://www.python.org/~guido/) ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )
