We are moving a site from one CMS to another. The .htaccess file has been changed and it needs to be refreshed for the new site to work right. From what I understand the .htaccess file will only be refreshed if the browser cache is cleared? It is fine for those creating the site to clear our cache, but is there a way to get the users' browsers to get the new .htaccess file without the user clearing cache manually on his own initiative?
If you're using RewriteRule, just use R instead of R=301. For other purposes, you'll have to clear your browser cache whenever you change a redirect.
Some servers will reload as soon as you replace the .htaccess file.
If so it instantly be used for all subsequent requests. You do not need to refresh any caches.
Some servers only check htaccess periodically.
I had a rewriterule in my .htaccess file like,
RewriteCond %{HTTPS} !on
RewriteRule (.*) https://example.com%{REQUEST_URI} [L,R=301]
and once I opened the site in localhost it never gave me a chance to hard refresh the page.
Solution: I added a random string like localhost/mywebsite/index.php?1234
