If your pages are the same for all users, and you run a proxy server in
front of your application server, you can set the proxy to cache the
pages for you.  This has some advantages, including excellent speed and
proper handling of If-Modified-Since and byte-range requests.  It also
keeps the load completely off your app server, freeing it for dynamic
requests.

The downside is that clearing an individual page from the cache before
the time you set in your Expires header is not trivial.  This may have
been improved with the recent changes to proxy caching in the apache 2.2
branch.
