How does one guarantee that the latest changes to the website will be served to browsers instead of browser just using the cached version?
I mean, we look at news websites and we don't read old news everyday. We can trust our browsers that they are picking up the latest changes to the news website.
But when I have changed my website, my mate can't see the changes.
There must be some file or code you put in a website to "push" the browser to not serve the cached version, but get the latest version off the server.
