I ran across a problem on a site today where some custom voting code had stopped working correctly. Eventually, I figured out that the actual problem was due to the page being cached, so it wasn't showing the updated results. I didn't want to turn off caching so, my next step was to figure out how to turn caching off for a particular page. The Google found CacheExclude, a module that allows you to do just that-- turn caching off for specific pages.
