Change caching directives. Used to be that all of the pages we spit
out included directives to prevent caching along the way. Now we look at the protocol (http vs https) and include directives that allow (encourage) http pages to be cached for a short time. My reasoning is that anything we spit out via http is documentation, and can grow a bit stale. Sure, the menu on the left is dynamic, but not so dynanic that it can't go a little stale too for people who are not logged in.
