Question

So I’ve got content at some site (example.com/stuff.html), and I upload a new stuff.html file. But when a user goes and looks at the page, they see the old content instead of the new content. If they refresh the page (typically by pressing F5), the new content shows up.

How should I mark the new stuff.html so it shows up first, instead of a previous version?

(I imagine this has something to do with the user’s browser caching pages, but I’m not too sure.)

Answer 1

There are several parameters to control browser caching that may be specified in meta tag. See http://www.i18nguy.com/markup/metatags.html

However usually it’s a web server’s responsibility to return new content or appropriate HTTP status code in case content isn’t changed.
