title: Force browsers to forget cached redirects?
body: <p>I inherited a domain that previously had a 301 redirect from the root ("/") to "/index.shtml"</p>
  
  <p>I've removed the redirect and a different site on the domain, but people who visited the site in the past will have the redirect behavior cached in their browsers... for a terribly long time, unless they manually clear their caches.</p>
  
  <p>Anyone trying to go to example.com in these browsers will be sent to example.com/index.shtml before they even make any HTTP requests. Right now this is a huge problem because there is no index.shtml, but is there something I can do with headers to tell browsers to "forget about that redirect you just did!"?</p>
