Cache considerations for web editors
Warning: Clearing the cache can have annoying consequences. After clearing your cache, you should browse a news site for a small while to fill up the browser's cache space that you just cleared down. If you don't do this, your browser may cache parts (or all) of pages you visit regularly - and if this happens, your browser will begin showing you those pages as they looked the day you cleared your cache - instead of showing their current contents.
