That's a good point. I mainly use it for browsing websites that change daily as well as ones with many successive pages, e.g., 1, 2, 3, etc. that IA does automatically not crawl. Thus, not many existing copies if any. HAproxy changes the Host header and modifies the URL. I can either use the text-only browser's http-proxy option or I can direct the request to the web.archive.org backend by adding a custom HTTP header to the request. If I am not mistaken, the so-called "modern" browsers do not have built-in capability to add headers.
