Browser Local Cache and Version Control

Let’s talk about the web browser. The browser is capable of storing a local copy of the assets (stylesheets, scripts, etc.). It does this to save web page load time. After the first visit to a page, the next time the person comes to the same page, it will load faster. Why? The browser doesn’t have to request those files from the server again. Nope, it kept a local copy in the computer’s cache.

In this episode, you will also see how WordPress appends the version on to the end of the asset’s URL in order to make it unique and give you the ability to make the browser request the new file.
