It might be a “permanent redirection” issue. A web server can redirect your request in a couple of ways. One of them is with a permanent redirct. This tells your browser what the redirected URL, and instructs your browser to use that in the future.
For examlpe,
- The published URL is
example.com/v1.html. - The server has a permanent redirct of
v1.htmltov2.html. - Your browser requests v1.html and the server supplies v2.html (even though it displays v1.html), and tells browser to use v2 in the future.
- The next time v1 is needed, the browser knows to ask for v2, saving the server from having to do the redirect.
Redirection info would be saved in the browsers cache. This could exain why different users see different results. Some might have the redirect “stuck” in their cache.
