Clear Browser Cache

To get cookies to work properly, you may have to clear your browser's cache so that the new HTML page / code is recognized by your browser.

So then, why does it seem as thought the images are stuck and won't update? What's going on here?

Here's a brief summary. Your web browser saves (caches) a copy of every page you display so that when you return to the page (without explicitly reloading) the browser can load its copy of the page and save having to pull another copy of the page across the Internet. This means faster browsing and less time waiting for a page to load. However, sometimes browsers hang onto their local copies longer than they should, and you can end up viewing an out-of-date page. With slow-changing websites this is usually not a problem. But, with the GOES website, the images are updated every 30 minutes.

Some users set their browser preferences to check every single time they visit a web site, effectively eliminating this problem, but that slows down your session with the extra chatter necessary between your browser and the Internet, reducing the speed savings of the (normally well-behaved) cache files. Most folks just set their browser cache check to "Automatic" or "First Time Each Session" (depending on browser type and version). Savvy users reload everything anyway having learned to never trust their computers. Top-notch users periodically flush out their browser caches as a general maintenance and preventative procedure.

Then there is the misbehaving firewall/proxy server problem, which is outside of both our hands and yours, generally requiring the intervention of your ISP's technicians or your system administrators to correct the problem.

If reloading or refreshing doesn't update the homepage and you think it should, then see the following section "The Stuck Browser Cache Fix" for ways to fix that problem.
