What is Browser Cache?
Browser cache is a technology used by most popular web browsers to save visited website’s data on a user’s computer. This allows the browser to quickly display a webpage on your next visit.
The logic behind it is that downloading static files from a WordPress hosting server located far away will take more time than reusing the resources from the user’s computer. This reduces the overall page load time and makes your online experience faster.
Why browsers cache static content?
Browser cache static content because it does not change as often as dynamic content.
For example, if you visit a WordPress website then the content of your posts and pages is more likely to change than your WordPress theme.
This is why browsers keep a copy of these static files in a temporary storage folder on your computer, so they use that copy on your next website visit.
If you are using a WordPress caching plugin, then it may add guidelines for browsers to cache your static content along with expiration instructions for each resource type.
This improves user experience and makes the internet faster for everyone.
Why and when you need to clear browser cache?
Most popular browsers are smart about deciding which content to store in cache.
However, sometimes they are unable to figure out that the website you are viewing has changed. In that case, browsers will still load the cached version of files from local storage.
This leads you to see an outdated version of a web page, and the website may not work as intended. If you have made some changes to your website, then you may not see them appear on the live site.
This is when you need to force reload that page in other words clear your browser cache.
