Page Caching

[Webnet]

This web site has great caching, if I'm viewing the board index, view a bard, then hit back, it loads the cache. How do I get my site to do that?

This is a good read

Sitepoint seems to focus on making sure external page objects(image, css, script etc...) are served with freshness info like max-age and etag headers.

I'll be sure to read through that next time I have some time.
