Feature Proposal: Performance With Apache ModCache
Motivation
Caching using apache module could lead to improve caching with few coding effort.
Description and Documentation
The apache mod_cache module seems to be mature enought by now to help improve TWiki's performance. Using this apache standard module would not affect coding, just configuration :
Examples
- Images and files located in the twiki/pub directory

mod_cache adds little on top of enabling ETags and the mod_expire settings - which I Blogged about and added to the
ApacheConfigGenerator many months ago - which avoids having a browser re-request the static files, thus saving the server in many more ways.
It would be interesting to know some actual performance numbers - I tried out mod_cache last year, and found that it wasn't an improvement.

How does this relate to
CacheControlHeaders? There are some useful links at
BrowserAndProxyCacheControl and
CategoryCaching. Generally I see HTTP headers that control caching as a useful add-on to server-side caching, but it's not easy to get this right in all cases particularly with dynamic pages.
