XF 1.5 Forcing HTTPS with .htaccess does not work with XenForo

[JackieChun]

After recently installing an SSL certificate, I enabled the following rule in .htaccess:

RewriteCond %{HTTPS} !=on
RewriteRule ^.*$ https://%{SERVER_NAME}%{REQUEST_URI} [R,L]

Strangely, it works for everything except XenForo. So if you type in http://example.com, it properly redirects to https://example.com. Same with http://example.com/anyrandomdirectory/, it goes to https://. But if you type http://example.com/xenforodirectory/, it does not redirect to https://. This has left me quite stumped. I have no idea what could be causing this and how to troubleshoot it.

You'll need to add this to your xenforodirectory .htaccess as well (just after the RewriteEngine On line).

How is it that rules in the root .htaccess file work on all subdirectories but not /xenforodirectory?

XenForo uses its own rewrite rules that match the URL and stop processing. You'd see this with various other applications as well.

Generally speaking a server will look for the nearest matching htaccess. So because XF's htaccess is nearer than the parent/root it will use that one.
