Clear WordPress cache is standard advice you will get during the WordPress troubleshooting.
Web browser, hosting servers, caching plugins, and even proxies store cache and serve content from there. Caching improves the loading speed of web pages, but it loads the outdated content.
You need to clear WordPress cache after updating the content, so the updated content loads from the webserver, instead of the user’s browser.
In this quick tutorial, I will show you how to clear the WordPress cache with the popular caching plugins.
How Does Cache Work?
When you put an URL to the browser and loads it, the browser sends the request to a web server for the content to load on the URL. Web server read the request and responds with the files.
Caching reduce the time it takes in the request-response cycle of web browser and the webserver. The data is stores as cache files in the browser, on the server, and some time in proxies. So for the next visit, only the fresh and dynamic data is fetched from the web server, while the static and repetitive data loads from the cache.
This way, the web page loads quickly due to the reduce network latency.
Browser and web server do not have to transfer the same data every time the page is fetched, and it saves the user’s time. Caching is a standard web optimisation technique.
Setting a time range for cached content is possible. You can select a different type of content to get deleted after some time. For example, images rarely get updates so that the cache life could be in months. Similarly, the text is frequently updated so that you can set the cache life for weeks.
After the set time, the cache will automatically be deleted, and the browser has to fetch the content directly from the web server, which means updated and fresh content.
When a site owner makes changes to the webpage, some times, the user loads the outdated content due to the cache. The webmaster should purge the cache so that the fresh content could be fetched instead of old copies.
