has anyone got a way to modify the mod_expires directives so that individual files can be cached, or if this is even a good idea?
To illustrate - here are the cache performance stats for moodle.org (this page)
|Empty Cache||Primed Cache|
In other words, 79% (!) of the page load of moodle.org with a primed cache is taken up by its style sheet. The numbers are roughly the same for my site.
Am I right in thinking its possible to gain a large decrease in page load time?
