What happens if you do not Clear your Browser's Cache?
Loading may not success. Mostly, it fails to load a webpage. I was uploading something, when i click on upload, it just brings me back to the hompage.


Why is it needed to clear your Browser's Cache?
All those files stored in your cache take up space, so from time to
time, you may want to clear out the files stored in your cache to free
up some space on your computer. This is called clearing the cache.
Often referred to as the cache, the Temporary Internet Files folder
contains a kind of travel record of the items you have seen, heard, or
downloaded from the Web, including images, sounds, Web pages, even cookies. Typically these items are stored in the Temporary Internet Files folder.Storing
these files in your cache can make browsing the Web faster because it
usually takes your computer less time to display a Web page when it can
call up some of the page's elements or even the entire page from your
local Temporary Internet Files folder.

1. After the browser opens, click on "Tools".
