Alternative Apache file caching system

Is it worth considering an Apache file caching system?

The technique uses canonical file names instead of the CI's time-stamp file naming system. I used file get parameters to:

1. display all cache files
2. delete all cache files
3. delete single files

Edit:
Please note that I am currently having MySql memory problems which may cause the site not to render. Hopefully getting CI to run in 512Mb will be solved today
