How to Clear Your Browser Cache
If you simply need a quick way to clear your cache, most modern browsers support the ctrl-shift-del (Option-Command-E for Safari users)key combination to bring up the privacy settings dialog. Once this dialog is on your screen, simply select the ‘cache’ option from the settings available, and continue. If this method does not work for you, please find your browser and version below for specific instructions.
Be aware that there are external caches that can be outside your control, in these instances we recommend that you allow up to 36 hours for those caches to clear.
