How to Configure Cache Settings:

An Internet browser's cache can come in handy. It does stores the information of all the websites you have viewed, so the next time you visit a particular site, it will load much quicker. However, it is good to periodically clean your cache settings, because eventually they will begin to slow down the actual performance of the computer. This is an easy step by step guide to clear your cache settings for Internet Explorer, Firefox and Safari.

On your Internet Explorer menu go the "Tools" tab and select "Internet options." When you do this, the "Internet options" window will appear on your screen. In the new window select the "General." This tab will appear by default. In the general tab click the "Settings" button. Now the settings window will pop up.In the section labeled "Check for new versions of stored pages" choose "Every visit to this page" and click "OK."When this is complete click "OK" again.
Step-2
2.For Safari:
Safari might have the fewest steps for clearing out your cache settings.First, go to the "Safari" tab in the upper left corner, directly next to the apple tab. Click on "Safari," and a drop-down menu will appear. Click on "Empty cache."Once you do, a prompt window will open explaining what exactly a cache is and asking if you really want to empty the cache. To proceed with clearing the cache, click "Empty."
Step-3
3.For Firefox:
From your Firefox menu go up to the "Tools." In the drop-down selections click on "Clear Private Data."A prompt window will now appear with an assortment of selections you can clear. Toward the middle, located next to the "Cookies" selection, is "Cache." Select this (as well as any of the other options) and click the "Clear private data now" button.Once you do this, if you are in a specialized account where you had to log in (such as Facebook), you will have to log back into your account before you can navigate it further.

Warning!!
Clearing out your cache actually slows down your Internet browsing. What a cache does is save the sites you have visited, so when you return back your computer remembers them and loads from the previous time you were there. However, if you do not clean your cache periodical, it will begin to take up large amounts of memory and can slow down your computer. Cleaning it is also a good way to remove some of the traces of sites you have been to that you don't want other users of the computer to see.
