Many people who search websites have probably come across the word cache. However, only a few who understand information technology may really understand what it means. Well, the details and technology of caching is complex. However, the idea behind it is very simple.
Within a month, people may view websites several times, even in millions. Each time browsers request particular web pages; servers must do several complex and time-consuming calculations. They retrieve the latest posts, generate headers and footers, and find sites’ sidebar widgets, among other things.
Often, the results of these calculations are the same. If the server could remember the final results, that would be wonderful. There is a way to make this possible. It is called caching. It just requires minimal modifications to the web page without interfering with loading time.
Serving Cached Pages
Someone who visits a website’s homepage that is caching enabled for the first time receives the page normally. First, the server receives the request, processes it, and turns the preliminary web page into an HTML file before sending it to the browser of the visitor.
Since caching is enabled, the server can store the HTML file in its RAM (random access memory). It is usually a very fast memory. The server doesn’t have to process the HTML file the next time anyone visits the same homepage. It just sends the available prepared file.
In case the website owner publishes a new post, proper caching systems can handle the case in a very simple manner. They ensure that the post is still visible to site visitors if users meet specific conditions of publishing new content. The systems do this by emptying and regenerating the cache.
Using Caching WordPress Plugins
Users should never employ more than one plugin. It is very dangerous. It does not only slow down a website but may also break it down. The use of a single, good, and well-configured caching system speeds up a site by as much as 300%. Some of the best systems to use on WordPress are Path browser plugins.
Using Host’s Caching
Hosting companies use caching systems that run at much lower levels than WordPress plugins. Therefore, they are much more effective. The providers also fine tune them to work with WordPress and other hosting environments, increasing their utility.
Those using managed WordPress hosts should not use any caching plugin. Such hosts even prohibit the use of certain plugins. This is because they are already using some types of caching systems. If users utilized these plugins, they would interfere with their hosts’ systems.
How Effective Is Caching?
Well-configured websites pages can load in about 2 seconds. Many could argue that this is fast enough and, therefore, there is no need for caches. However, caching makes the load times even much faster. Also, it makes sites perform more effectively. As a result, they are prepared to handle sudden traffic changes more efficiently.
Begin Caching Your Web Pages
The caching technology helps increase the speed of web pages at no cost at all. The only thing that users need is some little knowledge. Correct use of caching results in substantively faster load times and decreases loads on servers. Why not try it today?
