What is my “cache” and why should I clear it?
Any sophisticated website you visit is actually a composition of dozens, hundreds or even thousands of files. Even websites supremely optimized for speed are likely loading tons of files at once to display content in your browser.
Browsers try to do their part to speed up the loading process. The first time you visit a site, your browser will “save” pieces of the site. Because your browser can display the files stored in its cache much faster than it can pull fresh files from a server, the next time you visit that site, the use of cached files will help cut down page load time.
It sounds like cache is a good thing, why have you asked me to remove those saved files?
Many times web developers have to make updates to the files that comprise your site in order to push a change or new feature live. If we change a file that your browser has cached, it’s going to keep serving the old, cached version of the file and you won’t see our most recent change. That’s why we ask you to clear your cache.
