Hi, I'm using Zope 2.3.2 with Apache and Rewrite Rules. I set up caching using mod_proxy with the following settings: CacheRoot "/var/cache/httpd" CacheSize 10240 CacheGcInterval 1 CacheMaxExpire 24 CacheLastModifiedFactor 0.1 CacheDefaultExpire 1 I then added the following to standard_html_header: <dtml-call "RESPONSE.setHeader('Expires', _.DateTime(_.DateTime().timeTime() + 3600).toZone('GMT').rfc822())"> <dtml-call "RESPONSE.setHeader('Last-Modified', bobobase_modification_time().toZone('GMT').rfc822())"> This works fine and everything gets cached. Then I removed the above calls and instead installed an Accelerated HTTP Cache Manager (and associated all my DTML Methods with it). This time no caching took place. I then unncommented the line that sets the Last-Modified header (line 175 in AcceleratedHTTPCacheManager.py). This time caching worked. Several posts on this list indicated that Last-Modified is not required for caching. If that's true, why can't I get caching to work without touching the source? Am I missing anything in my settings or in using the Cache Manager?
