How to Refresh Your Browsers Cache
Clearing Cache Memory
To ensure you see the latest version of a site you need to clear the cache memory. This is done by doing a force refresh by pressing both control and F5 buttons simultaneously on your keyboard (depending on your browser). Most times a simple force cache refresh won’t work and you need to clear the cache by hand. On this site you can find step by step guides for Chrome, Firefox 3, Firefox 2, Internet Explorer 8, Internet Explorer 7, Internet Explorer 6, Safari and more on how to refresh your cache.
Someone just told you to “force reload” your browser to fix something. Depending on your operating system all you need to do is the following key combination:
Windows: ctrl + F5
Mac/Apple: Apple + R or command + R
Cache And Privacy
Internet cache can be a threat to your privacy as everyone who has access to your computer can see some personal information by simply opening the cache folder.
Also when the cache fills up, performance can slow down and your hard drive may run out of space.
Internet Service Provider Cache
In the same way that your web browser has a cache of recent web pages, your Internet Service Provider (ISP) may be doing some caching on your behalf.
In some (rare) cases, even though you are using shift-refresh to get new data from a webpage, the pages still seem to be old. This may be because your Internet Service Provider also has a cache and their cache may not be set up quite right, and they are not downloading the latest web pages.
When you encounter this problem you will have to communicatie with your ISP to fix this problem
