Why clearing or refreshing your cache?
Your browser has a folder
in which certain items that have been downloaded are stored for future use. Graphic images (such as buttons and icons), photo's, and even
entire web pages are examples of items which are saved or cached. When visiting a webpage your browser checks if a copy of the files on
the page is in its cache already. If so, it will save the visitor some downloading and make webpages load faster. Some browsers refer to it's
cache as Temporary Internet Files
Cache refresh
There are some situations when bypassing your browser's cache is preferred. Just clicking the refresh button (or hitting F5) won't be
sufficient in this case, because this reloads the webpage while still using the old files from the cache. You need to refresh your cache first!
