Is there a way to get a web server to use memory caching, but in a way that plays well with Rails caching?
Apache has memory caching (mod_mem_cache), as I understand.... but we cannot use it because Rails sweepers cannot expire cached pages?
The reason I ask -- for all the talk about how fast Lighttpd is, it's not preferable to have a web server reading files off disk with every request? Or have I missed something?
I guess the ideal setup would involve something like Memcached. Somehow, the webserver would keep the most popular static items in Memcached. Anything not found in Memcached can be found in /public on disk. ActionController would expire items in Memcached as well as on the disk.
Something like this would give worthwhile performance boosts?
