Just released the version 2.1.0 of Lite Cache plugin has a nice new feature: it can cache only recent posts avoiding to fill up the cache folder with old posts page that have a very low traffic (and so there is no improvement in caching them).
This feature, even if really particular, has been suggested by a Hyper Cache user. Even on Hyper Cache it should be implemented but for him I resolved the problem stopping the cache with a custom piece of code.
Lite Cache can be configure to use a different cache folder useful for those installations where there is a dedicated “temp” folder (leaving the blog space clean of cached files).
Have a nice caching.
