Infrastructure Software

I've got a tomcat web server on a suse box. Wondering if any of my http requests are getting cached in a web cache (e.g. like a web browser cache, or the jvm cache for desktop machines). Asking because I need to cache some specific web files to speed things up.

And if these requests are cached, where would they be kept on the server? I've checked my /home/user dirs and it doesn't seem to have much.
