“What Is the Browser Cache Anyway?

Traffic from webservers to your computer faces several challenges. All the content of the website – images, videos, content and its design – need to be transferred at the most possible speed to the nowadays extremely impatient users. For this, it is helpful to download certain content only once and keep it on your computer when you revisit the website later.

Caching Means:  “Thanks, I Already Have This!

Imagine a communication between a webserver and your computer, your computer telling the webserver “actually I don’t need this image, I already have it”. That’s called caching. By the way, there are many types of caching, we only refer to the browser cache here.

Caching reduces the load time of a webpage considerably, it also reduces the bandwidth (the amount of data) that the webserver has to deliver.

Seriously? Expiration Dates for Images?

Caching not only applies to images, but also to videos, scripts, and styles a webpage contains. Similar to the milk and butter you buy in a supermarket, they come with an expiration date which is typically days, weeks, or months ahead – depending on whether it’s an image, a script, or a stylesheet that defines your font and font size.

So when someone asked you to clear your browser cache, he or she indicates that the version of a webpage you are seeing is not the latest. While refreshing the browser a few times sometimes helps, clearing the cache is the best way to move on and see the latest version.
