Welcome, in this tutorial we’ll briefly discuss website caching.
Website cache, or cash as it may properly be pronounced is intended to speed up your website when you have a lot of simultaneous visitors.
Typically when someone visits your home page for example, your website system reaches into your database, extracts your home page content and builds a copy of your home page on the fly to be served to your visitor. This typically happens in under a second, but it does require some computing power to do so. You can imagine that if you had hundreds of visitors all at once, your website would need to work very hard to build your pages to be displayed to all of your visitors. This has the potential to significantly slow down your website, or require the need to upgrade your hosting to add more computing power.
This is where caching comes in. With a caching system, your website only has to build your pages for the first visitor. A copy of the page that was built is then saved into your website’s so that when the next visitor comes along, your website doesn’t have to build the page on the fly, instead it can pulled from the cache that was already built. This allows your website to remain speedy, even when you have a lot of simultaneous visitors.
However, this sometimes poses a minor issue when you make changes to your pages. When you’ve saved your changes you may not see them on your website right away, this is because you’re viewing an older, previously built copy of the page. Typically it will only take a minute or two for your cache to store the updated copy. But if you want to see it right away, you can delete the old version from your cache. In this video we show you how to do it.
