This depends on the internet browser that you are using and the type of the operating system that runs your computer. For the Google Chrome browser that I am using on my computer, you need to go to the wrench icon located on upper right corner and click tools and clear browsing data. Clear download history, empty the cache and delete cookies of the other site data. Then reload the browser.
