Tips for resolving possible browser cache problems or forcing the browser to load a fresh copy of web site pages.


Most browsers, computer operating systems, and internet hardware (routers, etc.) employ some type of caching to reduce the amount of time needed to resolve the actual address of a web site. Sometimes a browser will cache information about a site that is no longer valid or doesn't match the actual content of the site on the server. When this happens, you may experience problems accessing the site from your computer, even though the site is actively working and available. This is usually caused by caching, where your computer or browser uses old information to try to reach the site, but it needs to update that information to find the site properly. Here are some tips for forcing your browser and computer to use current information instead of its obsolete cache data when trying to reach the site:

The easiest way to force most popular Windows browsers to retrieve a fresh copy of the image from the server is to press CTRL+F5 while viewing the page. In Chrome on a Mac, you can use Command + Shift + R to force the current page to reload with the new image. In Safari, try Cmd + Option + R to reload the current page without using the cache (be sure to use these keyboard shortcuts while viewing your website page). In most cases, this will force the browser to update its cache with the most recent version of the image.

If using CTRL+F5 to reload a page from the server does not resolve the issue, you may need to clear the cache altogether for your browser. Here are some additional tips for clearing the various temporary caches so your browser can reload the current information from your website:

Microsoft Edge Browser: To clear/reset your cache in Microsoft Edge, go to the Settings page and select the Privacy and Services option from the menu. Then scroll down the page and find the "Clear browsing data now" item and click the button "Choose what to clear" next to it. On the window that pops up, UNcheck all options except for "Cached images and files", which should remain checked. Select "All Time" for the Time Range at the top of the window, then click the "Clear Now" button at the bottom.

Firefox Browser: To clear/reset the cache in Firefox, use the Clear Private Data menu option to remove temporary cache files.

Google Chrome Browser: To clear/reset the cache in Chrome, go to the Settings page and select the Privacy and Security option from the menu and click the "Clear browsing data" option. On the window that pops up, UNcheck all options except for "Cached images and files", which should remain checked. Select "All Time" for the Time Range at the top of the window, then click the "Clear Data" button at the bottom.

Windows Operating System Cache: Clear your local Windows DNS cache which is responsible for resolving the location of your site. Bring up a command window by clicking Start, then Run, then enter "CMD" and press enter. In the command window that opens, enter the following command: IPCONFIG /FLUSHDNS {press enter}

Router Cache: If you are using a router, it may have its own internal cache. If possible, reboot the router to see if it will resolve the issue.

• If all else fails, try rebooting your computer after completing these steps, which may also help resolve the issue by helping to clear any additional caching being done by the operating system or other internet applications running on your computer.
