So you've created an update for your site. Fixed some CSS, updated some scripting, etc. Do the deployment and wait for the love and praises from the customer... Right?! "I don't see the change.". You'll respond with the common: "Did you try a different browser", did you clear your cache..." or the classic "Did you try turning it OFF an ON again". Often that does the trick. But isn't there an easier way to tell the browser to stop caching these files?
