Everything you need to know about caching

When someone visits a website, all kinds of different processes are performed so that a user gains access to use the website. Carrying out these processes can sometimes cost an unnecessary amount of time and capacity. Time and capacity could be better spent on other things. To avoid this situation, caching is used. With the help of caching, the loading time of a website is considerably reduced! What exactly is caching? And how exactly does it work? Read more about this in this article.

What is caching?

In short, caching stores data from a website for reuse. In that case, a copy of this web page is in fact made. The caching process retrieves data from the cache. Cache is a software or hardware component, which aims to store new data. This is done so that future requests of the same data can be retrieved. This will reduce the loading time of a page much shorter, so that data from that website can be retrieved and processed faster. Such a cache memory is also seen as a high-speed data storage layer.

Website caching is one of the most profitable technologies available for universal use today. This technology makes websites accessible faster. This will result in better SEO scores for the website administrator and a better user experience for the website user.

In short, the performance of the website is optimized in an effective way. So there is no reason why you should not want to apply website caching to your own website!

Using Caching

The caching process can best be described as one that looks at the way a page is displayed. The moment someone visits a website for the first time, the website opens in the normal way. Then the caching process begins. This process goes like this:

  • The request for access to the website is received;
  • This request is being processed;
  • The webpage that is displayed is converted to a WordPress file, for example;
  • This WordPress file is then stored on the RAM.

When the same visitor comes to the website for the second time, the prepared WordPress file is sent to the user’s browser. As a result, the loading speed of the website for the user will be much higher than last time. The image on the left shows how you can apply the caching process yourself on your own PC.

Emptying the cache

Despite the fact that the page is displayed faster, it can sometimes happen that old data is shown on a subsequent visit to that website. This happens because the browser had still saved locally. It is then useful to no longer retrieve the latest data locally, but from the server itself. To do this, the cache must first be emptied, so that the latest information can be retrieved again. Emptying the cache is different for each browser. See below the different options:
