Hi Zope Fans, Here are pointers to some Zope Documentation explaining several ways to improve Zope performance by pushing content out to static storage (file system) where it can be served by a "dumb" (fast!) http server. Dynamic Zope is wonderful, marvelous, but like many things perhaps it should be saved for those tasks where less sophisticated means are clearly inadequate. In other words, use the specialist when you need to, leave the rest to generics. http://www.zope.org/Members/rossl/ZMirror *requires license for comercial use* http://www.zope.org/Members/kslee/pseudo_image http://www.zope.org/Members/LiDongfeng/external_image Another item still eludes me, for I dimly recall a Tip or How-TO about redirecting a "file not found" error to Zope for dynamic generation of a page. On success, the new page can then be added to the file system, so next time the file will be served conventionally. My apologies to those who sincerely believe that Zope can be all things to all Web Surfers. The above is evidence that some folks have found a role for Zope as an enhancement to their Web Sites, rather than as the foundation. Later, Jerry S.

I do this (mix Apache- and Zope- served content) but for reasons of convenience rather than speed. As far as I can tell, Zope on decent modern hardware (with adequate memory) is quite capable of serving all but the largest of sites at decent speed, and load sharing through ZEO or a SQL backend should take care of the largest sites.

I've posted about this in the past. With Apache, you merely add a line such as: ErrorDocument 404 /Zope/notfound This assumes that you have a RewriteRule mapping '/Zope' to your root Zope folder, and a document 'notfound' designed to handle 404 errors. I don't use this for filesystem acceleration, but rather for dynamic error handling. If I can figure out where the client was trying to go, I can do better than "It ain't thar". Since the vast majority of my sites' pages have some dynamic content (usually keyed on the client's login) page-by-page cacheing is worse than useless for me. If speed ever becomes a serious concern for any of my sites, I'll probably use ZCache or some variant to cache bits of expensive data and page fragments. Cheers, Evan @ 4-am
