How does browser caching work?

When you surf the web, your browser is in constant communication with the host, making a ‘GET’ request for more Facebook posts as you scroll down your newsfeed, or sending your angsty musings to Tumblr’s database via ‘POST’. As you go from page to page, some of the things you’re requesting from the host server are redundant -- when you click from your newsfeed to your profile, for example, Facebook’s logo is going to stay the same. 

Instead of requesting the same data again from the server, your browser holds this information in a cache. Before making a request to the host, the browser will first check its cache to see if the item has already been accessed recently. 

Browser caching reduces page load times by storing copies of images, stylesheets, javascript, or the entire page so that the next time the user needs that resource, the browser doesn’t have to download it from the server again. 

The items in the cache will expire eventually, and there are different ways of handling when to make a request for updated information. I’m not going to get into that because I put off writing this post for too long and now I have to meet some people for dinner but I think that’s enough to appease an interviewer.
