How to empty your browser's cache.

Your Internet browser may download pages from the web and store them in its "cache." Then when you return to a web page, your computer quickly reloads the saved version, rather than re-downloading the page

The cache sometimes causes problems. If you enter a password wrong the first time, your browser may store the error page in its cache. Even if you re-enter the password properly, the browser may give you the stored error page, rather than re-sending your password and accessing the page you want.

Here's some handy advice on emptying (or "purging") your browser's cache, using a couple of the most common browsers:

To empty the cache in Microsoft Internet Explorer

1. From the Safety menu in the upper right, click Delete Browsing History
2. Deselect Preserve Favorites website data, and select Temporary Internet files and History.
3. Click Delete.

To empty the cache in Firefox:

1. From the Tools menu, select Clear Recent History.
2. From the Time range to clear: drop-down menu, select the desired range; to clear your entire cache, select Everything.
3. Click the down arrow next to "Details" to choose what history elements to clear (e.g., check Cookies to clear cookies). Click Clear Now.

To empty the cache in Safari:

1. On the Safari menu, select Reset Safari.
2. Check the boxes for Clear history and Empty the cache ONLY.
3. Click the Reset button.
