apache - How to force a browser to refresh a cached version of a webpage

Question

I have a website that because of an ill-prepared apache conf file has instructed users to cache a website URL several years into the future. As a result, when a person visits the site, they often make no attempt to even request the page. The browser just loads the HTML from cache.

This website is about to get a major update, and I would like for users to be able to see it. Is there a way for me to force a user to actually re-request the webpage? I fear that for some users, unless they happen to press F5, they may see the old webpage for several years.

Answer 1

Use different URLs. If the main entry point to your website (like the main index file) is cached, then you're screwed... maybe you should register another domain name?
