How to force Internet Explorer (IE) to REALLY reload the page?

1. Select Tools >> Internet Options.
2. Click the Settings button in Browsing History.
3. Select the Every time I visit the webpage radio button.
4. Click OK to close the Settings dialog.
5. Click OK to close the Internet Options dialog.

Since it's stated that IE8 is the browser, you can press F12 to open the development tools and select the Cache menu at the top and then always refresh from server to bypass cache.

In short, Press F12. Click Cache -> Always Refresh from Server

You can simply clear your cache here as well, if that is the desired action. The always refresh option is not a global option and will not hinder overall performance in IE.

IE7 also has development tools, but they must be installed separately. You can also use the IE8 dev tools to run the browser in IE7 mode.
